摘要
设 G 是 n 个顶点上的简单图，设 λ1,λ2,...,λn 为 G 的拉普拉奇特征值，G 的拉普拉奇埃斯特拉达指数定义为 LEE(G)=∑i=1neλi。考虑一个有 n≥3 个顶点、m ...本文章由计算机程序翻译，如有差异，请以英文原文为准。
Sharp lower bounds for the Laplacian Estrada index of graphs
Let G be a simple graph on n vertices, and let λ1,λ2,…,λn be the Laplacian eigenvalues of G. The Laplacian Estrada index of G is defined as LEE(G)=∑i=1neλi. Consider a graph G with n≥3 vertices, m ...
