Abstract

In the study of a graph theory, degrees of vertices and number of edges are among the important theoretical terms that are helpful in showing discrete structures and their properties. This study attempts to present the relationship between number of edges and degrees of vertices in a mixed graph.

Key words: Graph, directed graphs, undirected graphs, mixed graph, degree of vertex, number of edges.
