Factored lifts of graphs and their spectra: the Abelian case
Abstract
In this paper, we introduce the concept of factored lift, associated with a combined voltage graph, as a generalization of the lift graph. We present a new method for computing all the eigenvalues and eigenspaces of factored lifts when the underlying group is Abelian.
