Relation between the inertia indices of a complex unit gain graph and those of its underlying graph

Linear and Multilinear Algebra, 2020
A T -gain graph is a triple Φ = ( G , T , ϕ ) consisting of an underlying graph G = ( V ( G ) , E ( G ) ) , the circle group T = { z ∈ C : | z | = 1 } and a gain function ϕ : E → → T , such that ϕ ...

On the multiplicity of $A��$-eigenvalues and the rank of complex unit gain graphs

2021
Let $ =(G, ) $ be a connected complex unit gain graph ($ \mathbb{T} $-gain graph) on a simple graph $ G $ with $ n $ vertices and maximum vertex degree $ $. The associated adjacency matrix and degree matrix are denoted by $ A( ) $ and $ D( ) $, respectively. Let $ m_ ( , ) $ be the multiplicity of $ $ as an eigenvalue of $ A_ ( ) := D(
