Abstract
Semigraph was dened by Sampathkumar as a generalization of graph. In this paper incidence matrix which represents semigraph uniquely and characterization of such a matrix is obtained. Some properties of incidence matrix of semigraph are studied. Structure of incidence matrix of some special classes of semigraphs are obtained.
Keywords: Semigraph, Incidence matrix, i-semigraphical matrix.
