On Coalition Graphs and Coalition Count of Graphs

Swathi Shetty, Sayinath Udupa N. V., B. R. Rakshith

Let $G$ be graph with vertex set $V (G)$ and order $n$ . A coalition in a graph $G$ consists of two disjoint sets of vertices $V_{1}$ and $V_{2}$ , neither of which is a dominating set bu…

Secure coalitions in graphs

Swathi Shetty, Sayinath Udupa N. V., B. R. Rakshith

A secure coalition in a graph $G$ consists of two disjoint vertex sets $V_{1}$ and $V_{2}$ , neither of which is a secure dominating set, but whose union $V_{1} \cup V_{2}$ forms a secure d…

On the $A BS$ spectrum and energy of graphs

Swathi Shetty, B. R. Rakshith, Sayinath Udupa N.

Let $η_{1} \geq η_{2} \geq \dots \geq η_{n}$ be the eigenavalues of $A BS$ matrix. In this paper, we characterize connected graphs with $A BS$ eigenvalue $η_{n} > - 1$ . As…

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 $G = (V, E)$ be a simple graph. The concept of Inverse symmetric division deg index $(I S D D)$ 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, $E (G)$ is the sum of all absolute values of the eigenvalues of the adjacency matr…
