Abstract :

Degree square sum matrix $DSS(G)$} of a graph $G$ is a square matrix of order equal to the order of a graph $G$ with its $(i,j)^{th}$ entry as ${{d_i}^{2}+{d_j}^{2}}$ if $i\neq j$ and zero otherwise, where $d_i$ is the degree of the $i^{th}$ vertex of $G$. In this paper, we study degree square sum hyperenergetic, degree square sum borderenergetic and degree square sum equienergetic graphs.

Keywords :

Degree square sum matrix, degree square sum polynomial, degree square sum energy, degree square sum hyperenergetic graphs, degree square sum equienergetic graphs.
