图G的Resolvent Estrada指标是近年来引入的图的不变量,记作EEr(G)=∑i=1n(1-λi/n-1)-1.该文得出图Cn和Pn的Resolvent Estrada指标更为精确的上下界,利用Matlab软件得到当n较小时的EEr(Cn)和EEr(Pn)的准确值.
the Resolvent Estrada index of G is a recently introduced graph invariant , defined as EEr(G)=∑i=1n(1-λi/n-1)-1.In this paper ,we gived new lower and upper bounds for Resolvent Estrada index of graph Cn and Pn ,and obtained accurate value of EEr (Cn) and EEr (Pn) when n is minor by Matlab software.
