TITLE: A Note on the Nullity of Unicyclic Graphs
AUTHORS: Shengbiao Hu
KEYWORDS: Eigenvalues (of Graphs), Nullity, Unicyclic Graphs
JOURNAL NAME: Applied Mathematics, Vol.5 No.10, June 17, 2014
ABSTRACT: The nullity of a graph is the multiplicity of the eigenvalue zero in its spectrum. In this paper we show the expression of the nullity and nullity set of unicyclic graphs with n vertices and girth r, and characterize the unicyclic graphs with extremal nullity.
