S. P. KANNIGA DEVI*, K. NAGARAJAN

Abstract


In this paper, we introduce the concepts of divisor degree matrix DD(G) of a simple graph G and obtain eigenvalues of DD(G).  We also introduce divisor degree energy (DDE) of graphs denoted by EDD (G) and find DDE of some standard graphs and also we establish the relation between energy and DDE of graphs.


Keywords


Energy, Divisor degree matrix, Divisor degree energy, Eigenvalues.
