Abstract

The sum of absolute values of eigenvalues of distance matrix of a graph is defined as distance energy of graph. We investigate distance energy for the larger graph obtained from any arbitrary graph by means of various graph operations. The concept of equienergetic graph is also explored in the context of distance energy of graph.

Keywords and Phrases
