On the number of vertices of projective polytopes
Natalia García-Colín, Luis Pedro Montejano, Jorge Luis Ramírez Alfonsín
Let be a configuration of points in . What is the maximum number of vertices that can have among all the possible permissible projective transfor…
Rainbow simplices in triangulations of manifolds
Luis Montejano
Given a coloration of the vertices of a triangulation of a manifold, we give homological conditions on the chromatic complexes under which it is possible to obtain a rainbow simple…
Different versions of the nerve theorem and rainbow simplices
Frédéric Meunier, Luis Montejano
Given a simplicial complex and a collection of subcomplexes covering it, the nerve theorem, a fundamental tool in topological combinatorics, guarantees a certain connectivity of th…
Chomp on generalized Kneser graphs and others
Ignacio García-Marco, Kolja Knauer, Luis Pedro Montejano
In chomp on graphs, two players alternatingly pick an edge or a vertex from a graph. The player that cannot move any more loses. The questions one wants to answer for a given graph…
