The Bases Of a Class of Special Zero-Symmetric Sign Pattern Matrices
摘要
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.关键词
