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…
