Abstract

The energy of a graph $\Gamma$ is defined as the sum of the absolute values of its eigenvalues. In this article, we compute the energy of the Indu-Bala product of two regular graphs and establish bounds for its energy. Furthermore, we explore the concepts of equienergetic, borderenergetic, orderenergetic, and non-hyperenergetic graphs using the Indu-Bala product of two regular graphs.
