Abstract. In this paper, we introduced a new definition of edge extension of graphs(digraphs). The edge extensible class of graphs and the edge extensibility number of graphs are introduced. Furthermore, we characterized the edge extensibility number for some certain graphs.
Keywords: Extension of graphs(digraphs), Eulerian graphs(digraphs), Regular graphs(digraphs).
