On Tosha-degree of an Edge in a Graph

R. Rajendra, P. Siva Kota Reddy

Abstract

In an earlier paper,  we have introduced the Tosha-degree of an edge in a graph without multiple edges and studied some properties. In this paper, we extend the definition of  Tosha-degree of an edge in a graph in which multiple edges are allowed. Also, we introduce the concepts - zero edges in a graph, $T$-line graph of a multigraph, Tosha-adjacency matrix, Tosha-energy, edge-adjacency matrix and edge energy of a graph $G$ and obtain some results.

Keywords

Adjacency matrix, degree of a vertex, energy, line graph, Tosha-degree of an edge.
