Popis: We define an alternating zeta function of a digraph D, and give its determinant expression. We present a decomposition formula for the alternating zeta function of a group covering of D. Furthermore, we introduce an alternating L-function of D, and present a determinant expression of it. As a corollary, we present a decomposition formula for the alternating zeta function of a group covering of D by its alternating L-functions.
