## Abstract

Abstract In this paper, we obtain a decomposition formula for the zeta function of an oriented line graph of a regular covering of a graph G. Furthermore, we introduce an L-function of an oriented line graph L ⇒ ( G ) of G, and give a decomposition formula for the zeta function of an oriented line graph of a regular covering of G by L-functions of L ⇒ ( G ) . As a by-product, we obtain an L-function version of Bass's result.
