图度序列平方和的不等式

Inequalities of the square sum of the degree sequence of a graph

图的度序列是图论研究中的一个基本课题,给出并证明了有关图度序列平方和几个不等式的两个定理.

The degree sequence of a graph is a basic subject in the study of graph theory. In this paper, some inequalities related to the square sum of the degree sequence of a graph are proved, and the corresponding external graphs are also obtained.
