  • Inductive and divisional posets 
    Pagaria, Roberto; Pismataro, Maddalena; Tran, Tan Nhat; Vecchi, Lorenzo (Oxford : Wiley, 2023)
    We call a poset factorable if its characteristic polynomial has all positive integer roots. Inspired by inductive and divisional freeness of a central hyperplane arrangement, we introduce and study the notion of inductive ...
  • The Minkowski property and reflexivity of marked poset polytopes 
    Fang, Xin; Fourier, Ghislain; Pegel, Christoph ([Madralin] : EMIS ELibEMS, 2020)
    We provide a Minkowski sum decomposition of marked chain-order polytopes into building blocks associated to elementary markings and thus give an explicit minimal set of generators of an associated semi-group algebra. We ...
