  text: "An n-vertex graph is called C-Ramsey if it has no clique or independent set
    of size Clog2n (i.e., if it has near-optimal Ramsey behavior). In this paper,
    we study edge statistics in Ramsey graphs, in particular obtaining very precise
    control of the distribution of the number of edges in a random vertex subset of
    a C-Ramsey graph. This brings together two ongoing lines of research: the study
    of ‘random-like’ properties of Ramsey graphs and the study of small-ball probability
    for low-degree polynomials of independent random variables.\r\n\r\nThe proof proceeds
    via an ‘additive structure’ dichotomy on the degree sequence and involves a wide
    range of different tools from Fourier analysis, random matrix theory, the theory
    of Boolean functions, probabilistic combinatorics and low-rank approximation.
    In particular, a key ingredient is a new sharpened version of the quadratic Carbery–Wright
    theorem on small-ball probability for polynomials of Gaussians, which we believe
    is of independent interest. One of the consequences of our result is the resolution
    of an old conjecture of Erdős and McKay, for which Erdős reiterated in several
    of his open problem collections and for which he offered one of his notorious
    monetary prizes."

  text: "We classify contravariant pairings between standard Whittaker modules and
    Verma modules over a complex semisimple Lie algebra. These contravariant pairings
    are useful in extending several classical techniques for category O to the Miličić–Soergel
    category N . We introduce a class of costandard modules which generalize dual
    Verma modules, and describe canonical maps from standard to costandard modules
    in terms of contravariant pairings.\r\nWe show that costandard modules have unique
    irreducible submodules and share the same composition factors as the corresponding
    standard Whittaker modules. We show that costandard modules give an algebraic
    characterization of the global sections of costandard twisted Harish-Chandra sheaves
    on the associated flag variety, which are defined using holonomic duality of D-modules.
    We prove that with these costandard modules, blocks of category\r\nN have the
    structure of highest weight categories and we establish a BGG reciprocity theorem
    for N ."

  text: "We prove a generalised super-adiabatic theorem for extended fermionic systems
    assuming a spectral gap only in the bulk. More precisely, we assume that the infinite
    system has a unique ground state and that the corresponding Gelfand–Naimark–Segal
    Hamiltonian has a spectral gap above its eigenvalue zero. Moreover, we show that
    a similar adiabatic theorem also holds in the bulk of finite systems up to errors
    that vanish faster than any inverse power of the system size, although the corresponding
    finite-volume Hamiltonians need not have a spectral gap.\r\n\r\n"

  text: A domain is called Kac regular for a quadratic form on L2 if every functions
    vanishing almost everywhere outside the domain can be approximated in form norm
    by functions with compact support in the domain. It is shown that this notion
    is stable under domination of quadratic forms. As applications measure perturbations
    of quasi-regular Dirichlet forms, Cheeger energies on metric measure spaces and
    Schrödinger operators on manifolds are studied. Along the way a characterization
    of the Sobolev space with Dirichlet boundary conditions on domains in infinitesimally
    Riemannian metric measure spaces is obtained.

  text: 'We prove a general local law for Wigner matrices that optimally handles observables
    of arbitrary rank and thus unifies the well-known averaged and isotropic local
    laws. As an application, we prove a central limit theorem in quantum unique ergodicity
    (QUE): that is, we show that the quadratic forms of a general deterministic matrix
    A on the bulk eigenvectors of a Wigner matrix have approximately Gaussian fluctuation.
    For the bulk spectrum, we thus generalise our previous result [17] as valid for
    test matrices A of large rank as well as the result of Benigni and Lopatto [7]
    as valid for specific small-rank observables.'

  text: Many trace inequalities can be expressed either as concavity/convexity theorems
    or as monotonicity theorems. A classic example is the joint convexity of the quantum
    relative entropy which is equivalent to the Data Processing Inequality. The latter
    says that quantum operations can never increase the relative entropy. The monotonicity
    versions often have many advantages, and often have direct physical application,
    as in the example just mentioned. Moreover, the monotonicity results are often
    valid for a larger class of maps than, say, quantum operations (which are completely
    positive). In this paper we prove several new monotonicity results, the first
    of which is a monotonicity theorem that has as a simple corollary a celebrated
    concavity theorem of Epstein. Our starting points are the monotonicity versions
    of the Lieb Concavity and the Lieb Convexity Theorems. We also give two new proofs
    of these in their general forms using interpolation. We then prove our new monotonicity
    theorems by several duality arguments.

  text: In this paper, we investigate the distribution of the maximum of partial sums
    of families of  m -periodic complex-valued functions satisfying certain conditions.
    We obtain precise uniform estimates for the distribution function of this maximum
    in a near-optimal range. Our results apply to partial sums of Kloosterman sums
    and other families of  ℓ -adic trace functions, and are as strong as those obtained
    by Bober, Goldmakher, Granville and Koukoulopoulos for character sums. In particular,
    we improve on the recent work of the third author for Birch sums. However, unlike
    character sums, we are able to construct families of  m -periodic complex-valued
    functions which satisfy our conditions, but for which the Pólya–Vinogradov inequality
    is sharp.

    K. For α∈End(E), define Bα to be the OK-integral ideal generated by the denominator
    of x(α(P)+Q). Let O be a subring of End(E), that is a Dedekind domain. We will
    study the sequence {Bα}α∈O. We will show that, for all but finitely many α∈O,
    the ideal Bα has a primitive divisor when P is a non-torsion point and there exist
    two endomorphisms g≠0 and f so that f(P)=g(Q). This is a generalization of previous
    results on elliptic divisibility sequences.

  text: Take a rational elliptic curve defined by the equation y2=x3+ax in minimal
    form and consider the sequence Bn of the denominators of the abscissas of the
    iterate of a non-torsion point. We show that B5m has a primitive divisor for every
    m. Then, we show how to generalize this method to the terms of the form Bmp with
    p a prime congruent to 1 modulo 4.

  text: Let  be a sequence of points on an elliptic curve defined over a number field
    K. In this paper, we study the denominators of the x-coordinates of this sequence.
    We prove that, if Q is a torsion point of prime order, then for n large enough
    there always exists a primitive divisor. Later on, we show the link between the
    study of the primitive divisors and a Lang-Trotter conjecture. Indeed, given two
    points P and Q on the elliptic curve, we prove a lower bound for the number of
    primes p such that P is in the orbit of Q modulo p.

  text: In this article we prove an analogue of a theorem of Lachaud, Ritzenthaler,
    and Zykin, which allows us to connect invariants of binary octics to Siegel modular
    forms of genus 3. We use this connection to show that certain modular functions,
    when restricted to the hyperelliptic locus, assume values whose denominators are
    products of powers of primes of bad reduction for the associated hyperelliptic
    curves. We illustrate our theorem with explicit computations. This work is motivated
    by the study of the values of these modular functions at CM points of the Siegel
    upper half-space, which, if their denominators are known, can be used to effectively
    compute models of (hyperelliptic, in our case) curves with CM.
