  text: For a locally finite set in R2, the order-k Brillouin tessellations form an
    infinite sequence of convex face-to-face tilings of the plane. If the set is coarsely
    dense and generic, then the corresponding infinite sequences of minimum and maximum
    angles are both monotonic in k. As an example, a stationary Poisson point process
    in R2  is locally finite, coarsely dense, and generic with probability one. For
    such a set, the distributions of angles in the Voronoi tessellations, Delaunay
    mosaics, and Brillouin tessellations are independent of the order and can be derived
    from the formula for angles in order-1 Delaunay mosaics given by Miles (Math.
    Biosci. 6, 85–127 (1970)).

  text: We propose a characterization of discrete analytical spheres, planes and lines
    in the body-centered cubic (BCC) grid, both in the Cartesian and in the recently
    proposed alternative compact coordinate system, in which each integer triplet
    addresses some voxel in the grid. We define spheres and planes through double
    Diophantine inequalities and investigate their relevant topological features,
    such as functionality or the interrelation between the thickness of the objects
    and their connectivity and separation properties. We define lines as the intersection
    of planes. The number of the planes (up to six) is equal to the number of the
    pairs of faces of a BCC voxel that are parallel to the line.

  text: We present a simple algorithm for computing higher-order Delaunay mosaics
    that works in Euclidean spaces of any finite dimensions. The algorithm selects
    the vertices of the order-k mosaic from incrementally constructed lower-order
    mosaics and uses an algorithm for weighted first-order Delaunay mosaics as a black-box
    to construct the order-k mosaic from its vertices. Beyond this black-box, the
    algorithm uses only combinatorial operations, thus facilitating easy implementation.
    We extend this algorithm to compute higher-order α-shapes and provide open-source
    implementations. We present experimental results for properties of higher-order
    Delaunay mosaics of random point sets.

  text: Geometry is crucial in our efforts to comprehend the structures and dynamics
    of biomolecules. For example, volume, surface area, and integrated mean and Gaussian
    curvature of the union of balls representing a molecule are used to quantify its
    interactions with the water surrounding it in the morphometric implicit solvent
    models. The Alpha Shape theory provides an accurate and reliable method for computing
    these geometric measures. In this paper, we derive homogeneous formulas for the
    expressions of these measures and their derivatives with respect to the atomic
    coordinates, and we provide algorithms that implement them into a new software
    package, AlphaMol. The only variables in these formulas are the interatomic distances,
    making them insensitive to translations and rotations. AlphaMol includes a sequential
    algorithm and a parallel algorithm. In the parallel version, we partition the
    atoms of the molecule of interest into 3D rectangular blocks, using a kd-tree
    algorithm. We then apply the sequential algorithm of AlphaMol to each block, augmented
    by a buffer zone to account for atoms whose ball representations may partially
    cover the block. The current parallel version of AlphaMol leads to a 20-fold speed-up
    compared to an independent serial implementation when using 32 processors. For
    instance, it takes 31 s to compute the geometric measures and derivatives of each
    atom in a viral capsid with more than 26 million atoms on 32 Intel processors
    running at 2.7 GHz. The presence of the buffer zones, however, leads to redundant
    computations, which ultimately limit the impact of using multiple processors.
    AlphaMol is available as an OpenSource software.

  text: The depth of a cell in an arrangement of n (non-vertical) great-spheres in
    Sd is the number of great-spheres that pass above the cell. We prove Euler-type
    relations, which imply extensions of the classic Dehn–Sommerville relations for
    convex polytopes to sublevel sets of the depth function, and we use the relations
    to extend the expressions for the number of faces of neighborly polytopes to the
    number of cells of levels in neighborly arrangements.

  text: 'We characterize critical points of 1-dimensional maps paired in persistent
    homology geometrically and this way get elementary proofs of theorems about the
    symmetry of persistence diagrams and the variation of such maps. In particular,
    we identify branching points and endpoints of networks as the sole source of asymmetry
    and relate the cycle basis in persistent homology with a version of the stable
    marriage problem. Our analysis provides the foundations of fast algorithms for
    maintaining collections of interrelated sorted lists together with their persistence
    diagrams. '

  text: Given a locally finite X⊆Rd and a radius r≥0, the k-fold cover of X and r
    consists of all points in Rd that have k or more points of X within distance r.
    We consider two filtrations—one in scale obtained by fixing k and increasing r,
    and the other in depth obtained by fixing r and decreasing k—and we compute the
    persistence diagrams of both. While standard methods suffice for the filtration
    in scale, we need novel geometric and topological concepts for the filtration
    in depth. In particular, we introduce a rhomboid tiling in Rd+1 whose horizontal
    integer slices are the order-k Delaunay mosaics of X, and construct a zigzag module
    of Delaunay mosaics that is isomorphic to the persistence module of the multi-covers.

  text: Consider a random set of points on the unit sphere in ℝd, which can be either
    uniformly sampled or a Poisson point process. Its convex hull is a random inscribed
    polytope, whose boundary approximates the sphere. We focus on the case d = 3,
    for which there are elementary proofs and fascinating formulas for metric properties.
    In particular, we study the fraction of acute facets, the expected intrinsic volumes,
    the total edge length, and the distance to a fixed point. Finally we generalize
    the results to the ellipsoid with homeoid density.

  text: We define a new compact coordinate system in which each integer triplet addresses
    a voxel in the BCC grid, and we investigate some of its properties. We propose
    a characterization of 3D discrete analytical planes with their topological features
    (in the Cartesian and in the new coordinate system) such as the interrelation
    between the thickness of the plane and the separability constraint we aim to obtain.

  text: Discrete Morse theory has recently lead to new developments in the theory
    of random geometric complexes. This article surveys the methods and results obtained
    with this new approach, and discusses some of its shortcomings. It uses simulations
    to illustrate the results and to form conjectures, getting numerical estimates
    for combinatorial, topological, and geometric properties of weighted and unweighted
    Delaunay mosaics, their dual Voronoi tessellations, and the Alpha and Wrap complexes
    contained in the mosaics.

  text: Slicing a Voronoi tessellation in ${R}^n$ with a $k$-plane gives a $k$-dimensional
    weighted Voronoi tessellation, also known as a power diagram or Laguerre tessellation.
    Mapping every simplex of the dual weighted Delaunay mosaic to the radius of the
    smallest empty circumscribed sphere whose center lies in the $k$-plane gives a
    generalized discrete Morse function. Assuming the Voronoi tessellation is generated
    by a Poisson point process in ${R}^n$, we study the expected number of simplices
    in the $k$-dimensional weighted Delaunay mosaic as well as the expected number
    of intervals of the Morse function, both as functions of a radius threshold. As
    a by-product, we obtain a new proof for the expected number of connected components
    (clumps) in a line section of a circular Boolean model in ${R}^n$.

  text: Generalizing the decomposition of a connected planar graph into a tree and
    a dual tree, we prove a combinatorial analog of the classic Helmholtz–Hodge decomposition
    of a smooth vector field. Specifically, we show that for every polyhedral complex,
    K, and every dimension, p, there is a partition of the set of p-cells into a maximal
    p-tree, a maximal p-cotree, and a collection of p-cells whose cardinality is the
    p-th reduced Betti number of K. Given an ordering of the p-cells, this tri-partition
    is unique, and it can be computed by a matrix reduction algorithm that also constructs
    canonical bases of cycle and boundary groups.

  text: Representing an atom by a solid sphere in 3-dimensional Euclidean space, we
    get the space-filling diagram of a molecule by taking the union. Molecular dynamics
    simulates its motion subject to bonds and other forces, including the solvation
    free energy. The morphometric approach [12, 17] writes the latter as a linear
    combination of weighted versions of the volume, area, mean curvature, and Gaussian
    curvature of the space-filling diagram. We give a formula for the derivative of
    the weighted mean curvature. Together with the derivatives of the weighted volume
    in [7], the weighted area in [3], and the weighted Gaussian curvature [1], this
    yields the derivative of the morphometric expression of the solvation free energy.

  text: Rhombic dodecahedron is a space filling polyhedron which represents the close
    packing of spheres in 3D space and the Voronoi structures of the face centered
    cubic (FCC) lattice. In this paper, we describe a new coordinate system where
    every 3-integer coordinates grid point corresponds to a rhombic dodecahedron centroid.
    In order to illustrate the interest of the new coordinate system, we propose the
    characterization of 3D digital plane with its topological features, such as the
    interrelation between the thickness of the digital plane and the separability
    constraint we aim to obtain. We also present the characterization of 3D digital
    lines and study it as the intersection of multiple digital planes. Characterization
    of 3D digital sphere with relevant topological features is proposed as well along
    with the 48-symmetry appearing in the new coordinate system.

  text: "Various kinds of data are routinely represented as discrete probability distributions.
    Examples include text documents summarized by histograms of word occurrences and
    images represented as histograms of oriented gradients. Viewing a discrete probability
    distribution as a point in the standard simplex of the appropriate dimension,
    we can understand collections of such objects in geometric and topological terms.
    Importantly, instead of using the standard Euclidean distance, we look into dissimilarity
    measures with information-theoretic justification, and we develop the theory\r\nneeded

  text: "We study the topology generated by the temperature fluctuations of the cosmic
    microwave background (CMB) radiation, as quantified by the number of components
    and holes, formally given by the Betti numbers, in the growing excursion sets.
    We compare CMB maps observed by the Planck satellite with a thousand simulated
    maps generated according to the ΛCDM paradigm with Gaussian distributed fluctuations.
    The comparison is multi-scale, being performed on a sequence of degraded maps
    with mean pixel separation ranging from 0.05 to 7.33°. The survey of the CMB over
    \U0001D54A2 is incomplete due to obfuscation effects by bright point sources and
    other extended foreground objects like our own galaxy. To deal with such situations,
    where analysis in the presence of “masks” is of importance, we introduce the concept
    of relative homology. The parametric χ2-test shows differences between observations
    and simulations, yielding p-values at percent to less than permil levels roughly
    between 2 and 7°, with the difference in the number of components and holes peaking
    at more than 3σ sporadically at these scales. The highest observed deviation between
    the observations and simulations for b0 and b1 is approximately between 3σ and
    4σ at scales of 3–7°. There are reports of mildly unusual behaviour of the Euler
    characteristic at 3.66° in the literature, computed from independent measurements
    of the CMB temperature fluctuations by Planck’s predecessor, the Wilkinson Microwave
    Anisotropy Probe (WMAP) satellite. The mildly anomalous behaviour of the Euler
    characteristic is phenomenologically related to the strongly anomalous behaviour
    of components and holes, or the zeroth and first Betti numbers, respectively.
    Further, since these topological descriptors show consistent anomalous behaviour
    over independent measurements of Planck and WMAP, instrumental and systematic
    errors may be an unlikely source. These are also the scales at which the observed
    maps exhibit low variance compared to the simulations, and approximately the range
    of scales at which the power spectrum exhibits a dip with respect to the theoretical
    model. Non-parametric tests show even stronger differences at almost all scales.
    Crucially, Gaussian simulations based on power-spectrum matching the characteristics
    of the observed dipped power spectrum are not able to resolve the anomaly. Understanding
    the origin of the anomalies in the CMB, whether cosmological in nature or arising
    due to late-time effects, is an extremely challenging task. Regardless, beyond
    the trivial possibility that this may still be a manifestation of an extreme Gaussian
    case, these observations, along with the super-horizon scales involved, may motivate
    the study of primordial non-Gaussianity. Alternative scenarios worth exploring
    may be models with non-trivial topology, including topological defect models."

  text: "The order-k Voronoi tessellation of a locally finite set \U0001D44B⊆ℝ\U0001D45B
    decomposes ℝ\U0001D45B into convex domains whose points have the same k nearest
    neighbors in X. Assuming X is a stationary Poisson point process, we give explicit
    formulas for the expected number and total area of faces of a given dimension
    per unit volume of space. We also develop a relaxed version of discrete Morse
    theory and generalize by counting only faces, for which the k nearest points in
    X are within a given distance threshold."

  text: We use the canonical bases produced by the tri-partition algorithm in (Edelsbrunner
    and Ölsböck, 2018) to open and close holes in a polyhedral complex, K. In a concrete
    application, we consider the Delaunay mosaic of a finite set, we let K be an Alpha
    complex, and we use the persistence diagram of the distance function to guide
    the hole opening and closing operations. The dependences between the holes define
    a partial order on the cells in K that characterizes what can and what cannot
    be constructed using the operations. The relations in this partial order reveal
    structural information about the underlying filtration of complexes beyond what
    is expressed by the persistence diagram.

  text: Motivated by biological questions, we study configurations of equal spheres
    that neither pack nor cover. Placing their centers on a lattice, we define the
    soft density of the configuration by penalizing multiple overlaps. Considering
    the 1-parameter family of diagonally distorted 3-dimensional integer lattices,
    we show that the soft density is maximized at the FCC lattice.
