A matrix-weighted zeta function of a graph. (English) Zbl 1286.05100
Summary: We define a matrix-weighted \(L\)-function of a graph \(G\), and give a determinant expression of it. As a corollary, we present a decomposition formula for the matrix-weighted zeta function of a regular covering of \(G\) by a product of matrix-weighted \(L\)-functions of \(G\).
