摘要
设A是周期为P的n阶布尔矩阵,1≤i≤n,A的广义幂敛指数k(A,i)是使得Ak和Ak+p有i行对应相等的最小非负整数k.本文刻画了恰含d(1≤d≤n)个非零对角元的n阶布尔矩阵的广义幂敛指数的极矩阵.
Let A be an n x n Boolean matrix with period p, 1≤i≤n. The generalized index of convergence k(A, i) of A is the least nonnegative integers k such that i rows of Ak and Ak+p are mutually equal. We characterize the extremal matrices of generalized indices of convergence of the n×n Boolean matrices with exactly d (1≤d≤n) non-zero diagonal entries.
