The transformation of edge-regular and pseudo strongly regular graphs under graph operations

Jeepamol J Palathingal, Aparna Lakshmanan S, Greg Markowsky

The graph $G$ is said to be strongly regular with parameters $(n, k, λ, μ)$ if the following conditions hold: (1) each vertex has $k$ neighbours; (2) any two adjacent vertices of $G$ …

Spectrum of Strongly Regular Graphs under Graph Operators

Jeepamol J Palathingal, Aparna Lakshmanan S, Greg Markowsky

In this paper, we show that if G is strongly regular then the Gallai graph and the anti-Gallai graph of G are edge-regular. We also identify conditions under which the Gallai and a…

Impact of Some Graph Operations on Double Roman Domination Number

Anu V., Aparna Lakshmanan S.

Given a graph $G = (V, E)$ , a function $f : V \to {0, 1, 2, 3}$ having the property that if $f (v) = 0$ , then there exist $v_{1}, v_{2} \in N (v)$ such that $f (v_{1}) = f (v_{2}) = 2$ or th…
