摘要

对伴随图为无向图的某类零对称符号模式进行了研究.分析了该无向图中二部子图的不同位置

利用反证法得到该类零对称符号模式矩阵基指数的下界

利用符号模式矩阵的有关理论得到该类零对称符号模式矩阵基指数的上界

从而得到了该类零对称符号模式矩阵的基指数.

Abstract

A class of zero-symmetric sign pattern featuring undirected associated graphs was studied.Two subgraphs of the undirected graphs and its different positions were analyzed.The base's lower bound of this class of zero-symmetric sign pattern was obtained by using the reduction to absurdity.The upper bound was also obtained by using the relevant theories of sign pattern matrix.Thus the bases of the class of zero-symmetric sign pattern matrix were obtained.
