A decomposition formula for the Bartholdi zeta function of a hypergraph covering

Combinatorics 2025-12-02 v2

Abstract

It is shown by Mizuno and Sato that the Bartholdi zeta function of a covering graph is decomposed as a product of Bartholdi zeta functions of a base graph that are associated with representations. In this paper, we extend their result to the case of a hypergraph covering.
