Abstract

The nullity of a graph is defined to be the multiplicity of the eigenvalue zero in the spectrum of the adjacency matrix of the graph. In this paper, we obtain the nullity set of bipartite graphs of order n , and characterize the bipartite graphs with nullity n - 4 and the regular bipartite graphs with nullity n - 6 .
