The energy of a graph G, denoted by E (G), is defined as the sum of absolute values of all
eigenvalues of G. In (MATCH Commun. Math. Comput. Chem. 83 (2020) 631–633) it was …

Energy of a simple graph $ G $, denoted by $\mathcal {E}(G) $, is the sum of the absolute
values of the eigenvalues of $ G $. Two graphs with the same order and energy are called …

In this paper, we introduce the concepts of Harary Laplacian-energy-like for a simple
undirected and connected graph G with order n. We also establish novel matrix results in …

The energy of a graph G, denoted by E (G), is defined as the sum of absolute values of all
eigenvalues of G. A graph of order n, whose energy is less than n, ie, E (G)< n, is said to be …

Let G be a graph of order n, and let Δ (G), δ (G) and d¯ be the maximum, minimum and
average degrees of G, respectively. In 2020, Akbari and Hosseinzadeh proposed a …
