总离心率总离心多项式图运算Total Eccentricity Total Eccentricity Polynomial Graph Operations


Let G be a simple connected graph. The total eccentricity and total eccentricity polynomial of a graph G are defined as and , where denotes the eccentricity of vertex ν  in G. In this paper, the total eccentricity and total eccentricity polynomial of double cover graph and extended double cover graph and subdivision graph of a given graph under the graph operations are computed and the exact expressions and some bounds are given.
