Energy of signed graphs and the vertex cover number

Aniruddha Samanta, Deepshikha, Kinkar Chandra Das

The energy of a signed graph is the sum of the absolute values of the eigenvalues of its adjacency matrix . In this article, we prove that $\mathca…

Hoffman-type Results for the Sum of k Largest Eigenvalues of a Graph

Shaowei Sun, Mengyao Guo, Hongyan Ge +1

Let denote the sum of the largest eigenvalues of a graph . Motivated by the classical Hoffman program for the spectral radius of a graph, we investigate an additive…

Bounds on the Inverse symmetric division deg index and the relation with other topological indices of graphs

Kinkar Chandra Das, B. R. Rakshith, Wojciech Macek

Let be a simple graph. The concept of Inverse symmetric division deg index was introduced in the chemical graph theory very recently. In spite of this, a few pap…

On Energy of Graphs with Self-Loops

B. R. Rakshith, Kinkar Chandra Das, B. J. Manjunatha

Let G be a simple graph on n vertices with vertex set V(G). The energy of G, denoted by, is the sum of all absolute values of the eigenvalues of the adjacency matr…

Common neighborhood energies and their relations with Zagreb index

Firdous Ee Jannat, Rajat Kanti Nath, Kinkar Chandra Das

In this paper we establish connections between common neighborhood Laplacian and common neighborhood signless Laplacian energies and the first Zagreb index of a graph …
