On the construction of l-equienergetic graphs

S. Pirzada, Hilal A Ganie

For a graph with $n$ vertices and $m$ edges, having Laplacian spectrum $μ_{1}, μ_{2}, \dots, μ_{n}$ and signless Laplacian spectrum $μ_{1}^{+}, μ_{2}^{+}, \dots, μ_{n}^{+}$ , the Laplacian energy and…

Energy, Laplacian energy of double graphs and new families of equienergetic graphs

S. Pirzada, Hilal A Ganie

For a graph $G$ with vertex set $V (G) = {v_{1}, v_{2}, \dots, v_{n}}$ , the extended double cover $G^{*}$ is a bipartite graph with bipartition (X, Y), $X = {x_{1}, x_{2}, \dots, x_{n}}$ and $Y…

Energy of signed digraphs

S. Pirzada, Mushtaq A. Bhat

In this paper we extend the concept of energy to signed digraphs. We obtain Coulson's integral formula for energy of signed digraphs. Formulae for energies of signed directed cycle…
