    Stability properties of Plethysm: new approach with combinatorial proofs (Extended abstract) by Laura Colmenarejo

    Published 2015-01-01
    “…We show that these other plethysm coefficients count integer points in polytopes and we prove stability for them by exhibiting bijections between the corresponding sets of integer points of each polytope.…”

    Subword Complexes and Nil-Hecke Moves by M. A. Gorsky

    Published 2013-01-01
    “…We describe the transformations of such a complex induced by nil-moves and inverse operations on Q in the nil-Hecke monoid corresponding to W. If the complex is polytopal, we also describe such transformations for the dual polytope. …”

    All tight correlation Bell inequalities have quantum violations by Llorenç Escolà, John Calsamiglia, Andreas Winter

    Published 2020-02-01
    “…In geometric terms, this means that any correlation Bell inequality for which the classical and quantum maximum values coincide, does not define a facet, i.e., a face of maximum dimension, of the local (Bell) polytope. Indeed, using semidefinite programming duality, we prove upper bounds on the dimension of these faces, bounding it far away from the maximum. …”

    Algebraic shifting and strongly edge decomposable complexes by Satoshi Murai

    Published 2008-01-01
    “…Kalai and Sarkaria conjectured that if $\Gamma$ is a simplicial sphere then its algebraic shifting also satisfies (c) $\Delta (\Gamma) \subset \Delta (C(n,d))$, where $C(n,d)$ is the boundary complex of the cyclic $d$-polytope with $n$ vertices. We show this conjecture for strongly edge decomposable spheres introduced by Nevo. …”

    Robust H-infinity filtering of stationary continuous-time linear systems with stochastic uncertainties by Gershon, E, Limebeer, D, Shaked, U, Yaesh, I

    Published 2001
    “…The method proposed is also applied to the case where, in addition to the stochastic uncertainty, other deterministic parameters of the system are not perfectly known and are assumed to lie in a given polytope. The problem of mixed H2/H∞ filtering for the above system is also treated. …”

    Approximate counting in SMT and value estimation for probabilistic programs by Chistikov, D, Dimitrova, R, Majumdar, R

    Published 2017
    “…<p>#SMT, or model counting for logical theories, is a well-known hard problem that generalizes such tasks as counting the number of satisfying assignments to a Boolean formula and computing the volume of a polytope. In the realm of satisfiability modulo theories (SMT) there is a growing need for model counting solvers, coming from several application domains (quantitative information flow, static analysis of probabilistic programs). …”

    The short toric polynomial by Gábor Hetyei

We establish bijections between positive Chow cells and the following sets: (a) regular subdivisions of the hypersimplex into positroid polytopes, (b) the set of cones in the positive tropical Grassmannian, and (c) the set of cones in the positive Dressian. …”
