The spread of the unicyclic graphs
Let G be a simple connected graph with n vertices and n edges which we call an unicyclic graph. In this paper, we first investigate the least eigenvalue n(G), then we present two sharp bounds of the spread s(G) of G. AMS classification: 05C50 ,05C35 Key words: Unicyclic graph; Spread; Largest eigenvalue; Least eigenvalue.
