摘要
根据图论知识,借助非负矩阵对的伴随有向图(即双色有向图),来解决非负矩阵对本原指数问题.考虑一类双圈双色有向图,给出了本原条件、指数界,并对极图和指数集进行了刻画.
On the basis of the knowledge of graph theory, the problem of primitive exponent of nonnegative matrix pairs is resolved by means of the associated digraph of nonnegative matrix pair, i.e. two-colored digraphs. A class of two-cycled two-colored digraphs is considered to give the primitive condition and exponent bound; and the extremal graphs and exponent sets are characterized.
