Primitive Exponents of Special Two-colored Digraphs with Two Cycles
摘要
Abstract
A class of special two-colored digraphs with two cycles is studied using the methods of nonnegative matrix theory and graph theory,whose uncolored digraph consists of one n-cycle and one(mn-1)-cycle with r common arcs.Some primitive conditions,the upper bound on the exponents and the characterizations of the extremal digraphs are obtained.关键词
