直径为n-4谱半径第二小的连通图
The Connected Graphs of Diameter n-4 with the Second Smallest Spectral Radius
摘要
Abstract
Using graphical transformation and comparison of the characteristic polynomial of graph and other methods, the graphs with the fixed diameter and the vertices number are ordered according to the minimal spectral radius. The connected graphs with the vertices number and the diameter that have the second smallest spectral radius are determined.关键词
