On stratifications for planar tensegrities with a small number of vertices
Oleg Karpenkov, Jan Schepers, Brigitte Servatius
In this paper we discuss several results about the structure of the configuration space of two-dimensional tensegrities with a small number of points. We briefly describe the techn…
Unimodality questions for integrally closed lattice polytopes
Jan Schepers, Leen Van Langenhoven
It is a famous open question whether every integrally closed reflexive polytope has a unimodal Ehrhart delta-vector. We generalize this question to arbitrary integrally closed latt…
Arc Spaces and Rogers-Ramanujan Identities
Clemens Bruschek, Hussein Mourtada, Jan Schepers
Arc spaces have been introduced in algebraic geometry as a tool to study singularities but they show strong connections with combinatorics as well. Exploiting these relations we ob…
Gorenstein polytopes and their stringy E-functions
Benjamin Nill, Jan Schepers
Inspired by ideas from algebraic geometry, Batyrev and the first named author have introduced the stringy E-function of a Gorenstein polytope. We prove that this a priori rational…
Stringy Hodge numbers of strictly canonical nondegenerate singularities
Jan Schepers
We describe a class of isolated nondegenerate hypersurface singularities that give a polynomial contribution to Batyrev's stringy E-function. These singularities are obtained by im…
Covers of surfaces with fixed branch locus
Bas Edixhoven, Robin de Jong, Jan Schepers
Given a connected smooth projective surface X over the complex numbers, together with a simple normal crossings divisor D on it, we study finite normal covers Y of X that are unram…
