Some New Results on Energy of Graphs with Self Loops

Kalpesh M. Popat, Kunal R. Shingala

The graph $G_{\ddot{I}}ƒ$ is obtained from graph $G$ by attaching self loops on $\ddot{I}ƒ$ vertices. The energy $E(G_{\ddot{I}}ƒ)$ of the graph $G_{\ddot{I}}ƒ$ with order $n$ and eigenvalues $λ_1,λ_2,\dots,λ_n…
