This book is about graph energy. The authors have included many of the important results
on graph energy, such as the complete solution to the conjecture on maximal energy of …

Degree sequence measurements on graphs have attracted a lot of research interest in
recent decades. Multiplying the degrees of adjacent vertices in graph Ω provides the …

The Laplacian-energy like invariant LEL (G) and the incidence energy IE (G) of a graph are
recently proposed quantities, equal, respectively, to the sum of the square roots of the …

We only consider finite, undirected and simple graphs throughout this paper. Let G be a
graph with vertex set V (G) and edge set E (G). The degree of v∈ V (G), denoted by dG (v), is …

Abstract Let Γ=(G, σ) be a signed graph, where G is its underlying graph and σ its sign
function (defined on edges of G). A signed graph Γ′, the subgraph of Γ, is its signed TU …

The trace norm of a digraph D is the trace norm of its adjacency matrix A (ie the sum of the
singular values of A). In particular, when G is a graph then its trace norm is the well-known …
