A generalization of $q$-deformation of graphic arrangements to simplicial complexes

Combinatorics 2026-04-06 v2

Abstract

The purpose of this thesis is to introduce two new kinds of hyperplane arrangements, inspired by the graphic arrangements and qq-deformations of graphic arrangements. In this thesis, the author extends the definition of qq-deformation to simplicial complexes, with the conjecture by Nian, Tsujie, Uchiumi and Yoshinaga. The author also investigates a special case called graphic monomial arrangement, including the characteristic polynomials and freeness with a further extension to fields with primitive roots.
