Gain-line graphs via $G$ -phases and group representations

Matteo Cavaleri, Daniele D'Angeli, Alfredo Donno

Let $G$ be an arbitrary group. We define a gain-line graph for a gain graph $(Γ, ψ)$ through the choice of an incidence $G$ -phase matrix inducing $ψ$ . We prove that the switching eq…

A group representation approach to balance of gain graphs

Matteo Cavaleri, Daniele D'Angeli, Alfredo Donno

We study the balance of $G$ -gain graphs, where $G$ is an arbitrary group, by investigating their adjacency matrices and their spectra. As a first step, we characterize switching eq…
