  text: "Considering a continuous self-map and the induced endomorphism on homology,
    we study the eigenvalues and eigenspaces of the latter. Taking a filtration of
    representations, we define the persistence of the eigenspaces, effectively introducing
    a hierarchical organization of the map. The algorithm that computes this information
    for a finite sample is proved to be stable, and to give the correct answer for
    a sufficiently dense sample. Results computed with an implementation of the algorithm
    provide evidence of its practical utility.\r\n"

  text: 'We study the spectrum of a large system of N identical bosons interacting
    via a two-body potential with strength 1/N. In this mean-field regime, Bogoliubov''s
    theory predicts that the spectrum of the N-particle Hamiltonian can be approximated
    by that of an effective quadratic Hamiltonian acting on Fock space, which describes
    the fluctuations around a condensed state. Recently, Bogoliubov''s theory has
    been justified rigorously in the case that the low-energy eigenvectors of the
    N-particle Hamiltonian display complete condensation in the unique minimizer of
    the corresponding Hartree functional. In this paper, we shall justify Bogoliubov''s
    theory for the high-energy part of the spectrum of the N-particle Hamiltonian
    corresponding to (non-linear) excited states of the Hartree functional. Moreover,
    we shall extend the existing results on the excitation spectrum to the case of
    non-uniqueness and/or degeneracy of the Hartree minimizer. In particular, the
    latter covers the case of rotating Bose gases, when the rotation speed is large
    enough to break the symmetry and to produce multiple quantized vortices in the
    Hartree minimizer. '

  text: 'We consider the spectral statistics of large random band matrices on mesoscopic
    energy scales. We show that the correlation function of the local eigenvalue density
    exhibits a universal power law behaviour that differs from the Wigner-Dyson- Mehta
    statistics. This law had been predicted in the physics literature by Altshuler
    and Shklovskii in (Zh Eksp Teor Fiz (Sov Phys JETP) 91(64):220(127), 1986); it
    describes the correlations of the eigenvalue density in general metallic sampleswith
    weak disorder. Our result rigorously establishes the Altshuler-Shklovskii formulas
    for band matrices. In two dimensions, where the leading term vanishes owing to
    an algebraic cancellation, we identify the first non-vanishing term and show that
    it differs substantially from the prediction of Kravtsov and Lerner in (Phys Rev
    Lett 74:2563-2566, 1995). The proof is given in the current paper and its companion
    (Ann. H. Poincaré. arXiv:1309.5107, 2014). '

  text: "A class of valued constraint satisfaction problems (VCSPs) is characterised
    by a valued constraint language, a fixed set of cost functions on a finite domain.
    Finite-valued constraint languages contain functions that take on rational costs
    and general-valued constraint languages contain functions that take on rational
    or infinite costs. An instance of the problem is specified by a sum of functions
    from the language with the goal to minimise the sum. This framework includes and
    generalises well-studied constraint satisfaction problems (CSPs) and maximum constraint
    satisfaction problems (Max-CSPs).\r\nOur main result is a precise algebraic characterisation
    of valued constraint languages whose instances can be solved exactly by the basic
    linear programming relaxation (BLP). For a general-valued constraint language
    Γ, BLP is a decision procedure for Γ if and only if Γ admits a symmetric fractional
    polymorphism of every arity. For a finite-valued constraint language Γ, BLP is
    a decision procedure if and only if Γ admits a symmetric fractional polymorphism
    of some arity, or equivalently, if Γ admits a symmetric fractional polymorphism
    of arity 2.\r\nUsing these results, we obtain tractability of several novel and
    previously widely-open classes of VCSPs, including problems over valued constraint
    languages that are: (1) submodular on arbitrary lattices; (2) bisubmodular (also
    known as k-submodular) on arbitrary finite domains; (3) weakly (and hence strongly)
    tree-submodular on arbitrary trees. "

  text: Motivated by the significant performance gains which polar codes experience
    under successive cancellation list decoding, their scaling exponent is studied
    as a function of the list size. In particular, the error probability is fixed,
    and the tradeoff between the block length and back-off from capacity is analyzed.
    A lower bound is provided on the error probability under MAP decoding with list
    size L for any binary-input memoryless output-symmetric channel and for any class
    of linear codes such that their minimum distance is unbounded as the block length
    grows large. Then, it is shown that under MAP decoding, although the introduction
    of a list can significantly improve the involved constants, the scaling exponent
    itself, i.e., the speed at which capacity is approached, stays unaffected for
    any finite list size. In particular, this result applies to polar codes, since
    their minimum distance tends to infinity as the block length increases. A similar
    result is proved for genie-aided successive cancellation decoding when transmission
    takes place over the binary erasure channel, namely, the scaling exponent remains
    constant for any fixed number of helps from the genie. Note that since genie-aided
    successive cancellation decoding might be strictly worse than successive cancellation
    list decoding, the problem of establishing the scaling exponent of the latter
    remains open.

  text: This paper presents polar coding schemes for the two-user discrete memoryless
    broadcast channel (DM-BC) which achieve Marton's region with both common and private
    messages. This is the best achievable rate region known to date, and it is tight
    for all classes of two-user DM-BCs whose capacity regions are known. To accomplish
    this task, we first construct polar codes for both the superposition as well as
    binning strategy. By combining these two schemes, we obtain Marton's region with
    private messages only. Finally, we show how to handle the case of common information.
    The proposed coding schemes possess the usual advantages of polar codes, i.e.,
    they have low encoding and decoding complexity and a superpolynomial decay rate
    of the error probability. We follow the lead of Goela, Abbe, and Gastpar, who
    recently introduced polar codes emulating the superposition and binning schemes.
    To align the polar indices, for both schemes, their solution involves some degradedness
    constraints that are assumed to hold between the auxiliary random variables and
    channel outputs. To remove these constraints, we consider the transmission of
    k blocks and employ a chaining construction that guarantees the proper alignment
    of the polarized indices. The techniques described in this paper are quite general,
    and they can be adopted to many other multiterminal scenarios whenever there polar
    indices need to be aligned.

  text: Currently, there is much debate on the genetic architecture of quantitative
    traits in wild populations. Is trait variation influenced by many genes of small
    effect or by a few genes of major effect? Where is additive genetic variation
    located in the genome? Do the same loci cause similar phenotypic variation in
    different populations? Great tits (Parus major) have been studied extensively
    in long‐term studies across Europe and consequently are considered an ecological
    ‘model organism’. Recently, genomic resources have been developed for the great
    tit, including a custom SNP chip and genetic linkage map. In this study, we used
    a suite of approaches to investigate the genetic architecture of eight quantitative
    traits in two long‐term study populations of great tits—one in the Netherlands
    and the other in the United Kingdom. Overall, we found little evidence for the
    presence of genes of large effects in either population. Instead, traits appeared
    to be influenced by many genes of small effect, with conservative estimates of
    the number of contributing loci ranging from 31 to 310. Despite concordance between
    population‐specific heritabilities, we found no evidence for the presence of loci
    having similar effects in both populations. While population‐specific genetic
    architectures are possible, an undetected shared architecture cannot be rejected
    because of limited power to map loci of small and moderate effects. This study
    is one of few examples of genetic architecture analysis in replicated wild populations
    and highlights some of the challenges and limitations researchers will face when
    attempting similar molecular quantitative genetic studies in free‐living populations.

  text: Phenotypes expressed in a social context are not only a function of the individual,
    but can also be shaped by the phenotypes of social partners. These social effects
    may play a major role in the evolution of cooperative breeding if social partners
    differ in the quality of care they provide and if individual carers adjust their
    effort in relation to that of other carers. When applying social effects models
    to wild study systems, it is also important to explore sources of individual plasticity
    that could masquerade as social effects. We studied offspring provisioning rates
    of parents and helpers in a wild population of long-tailed tits Aegithalos caudatus
    using a quantitative genetic framework to identify these social effects and partition
    them into genetic, permanent environment and current environment components. Controlling
    for other effects, individuals were consistent in their provisioning effort at
    a given nest, but adjusted their effort based on who was in their social group,
    indicating the presence of social effects. However, these social effects differed
    between years and social contexts, indicating a current environment effect, rather
    than indicating a genetic or permanent environment effect. While this study reveals
    the importance of examining environmental and genetic sources of social effects,
    the framework we present is entirely general, enabling a greater understanding
    of potentially important social effects within any ecological population.

  text: We prove that nonlinear Gibbs measures can be obtained from the corresponding
    many-body, grand-canonical, quantum Gibbs states, in a mean-field limit where
    the temperature T diverges and the interaction strength behaves as 1/T. We proceed
    by characterizing the interacting Gibbs state as minimizing a functional counting
    the free-energy relatively to the non-interacting case. We then perform an infinite-dimensional
    analogue of phase-space semiclassical analysis, using fine properties of the quantum
    relative entropy, the link between quantum de Finetti measures and upper/lower
    symbols in a coherent state basis, as well as Berezin-Lieb type inequalities.
    Our results cover the measure built on the defocusing nonlinear Schrödinger functional
    on a finite interval, as well as smoother interactions in dimensions d 2.

  text: We consider two-player games played on weighted directed graphs with mean-payoff
    and total-payoff objectives, two classical quantitative objectives. While for
    single-dimensional games the complexity and memory bounds for both objectives
    coincide, we show that in contrast to multi-dimensional mean-payoff games that
    are known to be coNP-complete, multi-dimensional total-payoff games are undecidable.
    We introduce conservative approximations of these objectives, where the payoff
    is considered over a local finite window sliding along a play, instead of the
    whole play. For single dimension, we show that (i) if the window size is polynomial,
    deciding the winner takes polynomial time, and (ii) the existence of a bounded
    window can be decided in NP ∩ coNP, and is at least as hard as solving mean-payoff
    games. For multiple dimensions, we show that (i) the problem with fixed window
    size is EXPTIME-complete, and (ii) there is no primitive-recursive algorithm to
    decide the existence of a bounded window.

  text: 'We consider concurrent games played by two players on a finite-state graph,
    where in every round the players simultaneously choose a move, and the current
    state along with the joint moves determine the successor state. We study the most
    fundamental objective for concurrent games, namely, mean-payoff or limit-average
    objective, where a reward is associated to each transition, and the goal of player
    1 is to maximize the long-run average of the rewards, and the objective of player
    2 is strictly the opposite (i.e., the games are zero-sum). The path constraint
    for player 1 could be qualitative, i.e., the mean-payoff is the maximal reward,
    or arbitrarily close to it; or quantitative, i.e., a given threshold between the
    minimal and maximal reward. We consider the computation of the almost-sure (resp.
    positive) winning sets, where player 1 can ensure that the path constraint is
    satisfied with probability 1 (resp. positive probability). Almost-sure winning
    with qualitative constraint exactly corresponds to the question of whether there
    exists a strategy to ensure that the payoff is the maximal reward of the game.
    Our main results for qualitative path constraints are as follows: (1) we establish
    qualitative determinacy results that show that for every state either player 1
    has a strategy to ensure almost-sure (resp. positive) winning against all player-2
    strategies, or player 2 has a spoiling strategy to falsify almost-sure (resp.
    positive) winning against all player-1 strategies; (2) we present optimal strategy
    complexity results that precisely characterize the classes of strategies required
    for almost-sure and positive winning for both players; and (3) we present quadratic
    time algorithms to compute the almost-sure and the positive winning sets, matching
    the best known bound of the algorithms for much simpler problems (such as reachability
    objectives). For quantitative constraints we show that a polynomial time solution
    for the almost-sure or the positive winning set would imply a solution to a long-standing
    open problem (of solving the value problem of turn-based deterministic mean-payoff
    games) that is not known to be solvable in polynomial time.'

  text: "We consider Markov decision processes (MDPs) with multiple limit-average
    (or mean-payoff) objectives. \r\nThere have been two different views: (i) the
    expectation semantics, where the goal is to optimize the expected mean-payoff
    objective, and (ii) the satisfaction semantics, where the goal is to maximize
    the probability of runs such that the mean-payoff value stays above a given vector.
    \ \r\nWe consider the problem where the goal is to optimize the expectation under
    the constraint that the satisfaction semantics is ensured, and thus consider a
    generalization that unifies the existing semantics.\r\nOur problem captures the
    notion of optimization with respect to strategies that are risk-averse (i.e.,
    ensures certain probabilistic guarantee).\r\nOur main results are algorithms for
    the decision problem which are always polynomial in the size of the MDP. We also
    show that an approximation of the Pareto-curve can be computed in time polynomial
    in the size of the MDP, and the approximation factor, but exponential in the number
    of dimensions.\r\nFinally, we present a complete characterization of the strategy
    complexity (in terms of memory bounds and randomization) required to solve our
    problem."

  text: We consider the core algorithmic problems related to verification of systems
    with respect to three classical quantitative properties, namely, the mean- payoff
    property, the ratio property, and the minimum initial credit for energy property.
    The algorithmic problem given a graph and a quantitative property asks to compute
    the optimal value (the infimum value over all traces) from every node of the graph.
    We consider graphs with constant treewidth, and it is well-known that the control-flow
    graphs of most programs have constant treewidth. Let n denote the number of nodes
    of a graph, m the number of edges (for constant treewidth graphs m = O ( n ) )
    and W the largest absolute value of the weights. Our main theoretical results
    are as follows. First, for constant treewidth graphs we present an algorithm that
    approximates the mean-payoff value within a mul- tiplicative factor of ∊ in time
    O ( n · log( n/∊ )) and linear space, as compared to the classical algorithms
    that require quadratic time. Second, for the ratio property we present an algorithm
    that for constant treewidth graphs works in time O ( n · log( | a · b · n | ))
    = O ( n · log( n · W )) , when the output is a b , as compared to the previously
    best known algorithm with running time O ( n 2 · log( n · W )) . Third, for the
    minimum initial credit problem we show that (i) for general graphs the problem
    can be solved in O ( n 2 · m ) time and the associated decision problem can be
    solved in O ( n · m ) time, improving the previous known O ( n 3 · m · log( n
    · W )) and O ( n 2 · m ) bounds, respectively; and (ii) for constant treewidth
    graphs we present an algorithm that requires O ( n · log n ) time, improving the
    previous known O ( n 4 · log( n · W )) bound. We have implemented some of our
    algorithms and show that they present a significant speedup on standard benchmarks.

  text: "We consider finite-state concurrent stochastic games, played by k>=2 players
    for an infinite number of rounds, where in every round, each player simultaneously
    and independently of the other players chooses an action, whereafter the successor
    state is determined by a probability distribution given by the current state and
    the chosen actions. We consider reachability objectives that given a target set
    of states require that some state in the target set is visited, and the dual safety
    objectives that given a target set require that only states in the target set
    are visited. We are interested in the complexity of stationary strategies measured
    by their patience, which is defined as the inverse of the smallest non-zero probability
    employed.\r\n\r\n Our main results are as follows: We show that in two-player
    zero-sum concurrent stochastic games (with reachability objective for one player
    and the complementary safety objective for the other player): (i) the optimal
    bound on the patience of optimal and epsilon-optimal strategies, for both players
    is doubly exponential; and (ii) even in games with a single non-absorbing state
    exponential (in the number of actions) patience is necessary. In general we study
    the class of non-zero-sum games admitting epsilon-Nash equilibria. We show that
    if there is at least one player with reachability objective, then doubly-exponential
    patience is needed in general for epsilon-Nash equilibrium strategies, whereas
    in contrast if all players have safety objectives, then the optimal bound on patience
    for epsilon-Nash equilibrium strategies is only exponential."

  text: "Evolution occurs in populations of reproducing individuals. The structure
    of the population affects the outcome of the evolutionary process. Evolutionary
    graph theory is a powerful approach to study this phenomenon. There are two graphs.
    The interaction graph specifies who interacts with whom in the context of evolution.The
    replacement graph specifies who competes with whom for reproduction. \r\nThe vertices
    of the two graphs are the same, and each vertex corresponds to an individual of
    the population. A key quantity is the fixation probability of a new mutant. It
    is defined as the probability that a newly introduced mutant (on a single vertex)
    generates a lineage of offspring which eventually takes over the entire population
    of resident individuals. The basic computational questions are as follows: (i)
    the qualitative question asks whether the fixation probability is positive; and
    (ii) the quantitative approximation question asks for an approximation of the
    fixation probability. \r\nOur main results are:\r\n(1) We show that the qualitative
    question is NP-complete and the quantitative approximation question is #P-hard
    in the special case when the interaction and the replacement graphs coincide and
    even with the restriction that the resident individuals do not reproduce (which
    corresponds to an invading population taking over an empty structure).\r\n(2)
    We show that in general the qualitative question is PSPACE-complete and the quantitative
    approximation question is PSPACE-hard and can be solved in exponential time.\r\n"

  text: DEC-POMDPs extend POMDPs to a multi-agent setting, where several agents operate
    in an uncertain environment independently to achieve a joint objective. DEC-POMDPs
    have been studied with finite-horizon and infinite-horizon discounted-sum objectives,
    and there exist solvers both for exact and approximate solutions. In this work
    we consider Goal-DEC-POMDPs, where given a set of target states, the objective
    is to ensure that the target set is reached with minimal cost. We consider the
    indefinite-horizon (infinite-horizon with either discounted-sum, or undiscounted-sum,
    where absorbing goal states have zero-cost) problem. We present a new method to
    solve the problem that extends methods for finite-horizon DEC- POMDPs and the
    RTDP-Bel approach for POMDPs. We present experimental results on several examples,
    and show our approach presents promising results.

  text: "We consider Markov decision processes (MDPs) with multiple limit-average
    (or mean-payoff) objectives. \r\nThere have been two different views: (i) the
    expectation semantics, where the goal is to optimize the expected mean-payoff
    objective, and (ii) the satisfaction semantics, where the goal is to maximize
    the probability of runs such that the mean-payoff value stays above a given vector.
    \ \r\nWe consider the problem where the goal is to optimize the expectation under
    the constraint that the satisfaction semantics is ensured, and thus consider a
    generalization that unifies the existing semantics. Our problem captures the notion
    of optimization with respect to strategies that are risk-averse (i.e., ensures
    certain probabilistic guarantee).\r\nOur main results are algorithms for the decision
    problem which are always polynomial in the size of the MDP.\r\nWe also show that
    an approximation of the Pareto-curve can be computed in time polynomial in the
    size of the MDP, and the approximation factor, but exponential in the number of
    dimensions. Finally, we present a complete characterization of the strategy complexity
    (in terms of memory bounds and randomization) required to solve our problem."

  text: "Recently there has been a significant effort to handle quantitative properties
    in formal verification and synthesis. While weighted automata over finite and
    infinite words provide a natural and flexible framework to express quantitative
    properties, perhaps surprisingly, some basic system properties such as average
    response time cannot be expressed using weighted automata, nor in any other know
    decidable formalism. In this work, we introduce nested weighted automata as a
    natural extension of weighted automata which makes it possible to express important
    quantitative properties such as average response time.\r\nIn nested weighted automata,
    a master automaton spins off and collects results from weighted slave automata,
    each of which computes a quantity along a finite portion of an infinite word.
    Nested weighted automata can be viewed as the quantitative analogue of monitor
    automata, which are used in run-time verification. We establish an almost complete
    decidability picture for the basic decision problems about nested weighted automata,
    and illustrate their applicability in several domains. In particular, nested weighted
    automata can be used to decide average response time properties."

  text: "We consider the core algorithmic problems related to verification of systems
    with respect to three classical quantitative properties, namely, the mean-payoff
    property, the ratio property, and the minimum initial credit for energy property.
    \r\nThe algorithmic problem given a graph and a quantitative property asks to
    compute the optimal value (the infimum value over all traces) from every node
    of the graph. We consider graphs with constant treewidth, and it is well-known
    that the control-flow graphs of most programs have constant treewidth. Let $n$
    denote the number of nodes of a graph, $m$ the number of edges (for constant treewidth
    graphs $m=O(n)$) and $W$ the largest absolute value of the weights.\r\nOur main
    theoretical results are as follows.\r\nFirst, for constant treewidth graphs we
    present an algorithm that approximates the mean-payoff value within a multiplicative
    factor of $\\epsilon$ in time $O(n \\cdot \\log (n/\\epsilon))$ and linear space,
    as compared to the classical algorithms that require quadratic time. Second, for
    the ratio property we present an algorithm that for constant treewidth graphs
    works in time $O(n \\cdot \\log (|a\\cdot b|))=O(n\\cdot\\log (n\\cdot W))$, when
    the output is $\\frac{a}{b}$, as compared to the previously best known algorithm
    with running time $O(n^2 \\cdot \\log (n\\cdot W))$. Third, for the minimum initial
    credit problem we show that (i)~for general graphs the problem can be solved in
    $O(n^2\\cdot m)$ time and the associated decision problem can be solved in $O(n\\cdot
    m)$ time, improving the previous known $O(n^3\\cdot m\\cdot \\log (n\\cdot W))$
    and $O(n^2 \\cdot m)$ bounds, respectively; and (ii)~for constant treewidth graphs
    we present an algorithm that requires $O(n\\cdot \\log n)$ time, improving the
    previous known $O(n^4 \\cdot \\log (n \\cdot W))$ bound.\r\nWe have implemented
    some of our algorithms and show that they present a significant speedup on standard
    benchmarks. "

  text: "The edit distance between two words w1, w2 is the minimal number of word
    operations (letter insertions, deletions, and substitutions) necessary to transform
    w1 to w2. The edit distance generalizes to languages L1, L2, where the edit distance
    is the minimal number k such that for every word from L1 there exists a word in
    L2 with edit distance at most k. We study the edit distance computation problem
    between pushdown automata and their subclasses.\r\nThe problem of computing edit
    distance to a pushdown automaton is undecidable, and in practice, the interesting
    question is to compute the edit distance from a pushdown automaton (the implementation,
    a standard model for programs with recursion) to a regular language (the specification).
    In this work, we present a complete picture of decidability and complexity for
    deciding whether, for a given threshold k, the edit distance from a pushdown automaton
    to a finite automaton is at most k. "
