Lattice point enumeration of polytopes associated to integer compositions
Christos A. Athanasiadis
An -dimensional lattice polytope can be associated to any composition of a positive integer , as a special case of constructions due to Pitman--Stanley a…
Reproducibility study of "LICO: Explainable Models with Language-Image Consistency"
Luan Fletcher, Robert van der Klis, Martin Sedláček +2
The growing reproducibility crisis in machine learning has brought forward a need for careful examination of research findings. This paper investigates the claims made by Lei et al…
A convex ear decomposition of the augmented Bergman complex of a matroid
Christos A. Athanasiadis, Luis Ferroni
In recent work of Braden, Huh, Matherne, Proudfoot and Wang, a class of simplicial complexes associated to matroids, called augmented Bergman complexes, was introduced. The present…
Veronese sections and interlacing matrices of polynomials and formal power series
Christos A. Athanasiadis, David G. Wagner
The concept of a fully interlacing matrix of formal power series with real coefficients is introduced. This concept extends and strengthens that of an interlacing sequence of real-…
Local -polynomials, uniform triangulations and real-rootedness
Christos A. Athanasiadis
The local -polynomial was introduced by Stanley as a fundamental enumerative invariant of a triangulation of a simplex. This polynomial is known to have nonnegative and symm…
Two classes of posets with real-rooted chain polynomials
Christos A. Athanasiadis, Theo Douvropoulos, Katerina Kalampogia-Evangelinou
The coefficients of the chain polynomial of a finite poset enumerate chains in the poset by their number of elements. It has been a challenging open problem to determine which pose…
