Enumerating chambers of hyperplane arrangements with symmetry

Taylor Brysiewicz, Holger Eble and Lukas Kühne

Abstract

We introduce a new algorithm for enumerating chambers of hyperplane arrangements which exploits their underlying symmetry groups. Our algorithm counts the chambers of an arrangement as a byproduct of computing its characteristic polynomial. We showcase our julia implementation, based on OSCAR, on examples coming from hyperplane arrangements with applications to physics and computer science.
