THE INDICES OF CONVERGENCE FOR IRREDUCIBLE AND NEARLY REDUCIBLE BOOLEAN MATRICES
<正> The index of convergence k(A)of a square Boolean matrix A is defined to be the least nonnegative integer k such that A~k= Ak~1 for some k_1>k; and the index of convergence k(D) of a digraph D is just the index of convergence of the adjacent matrix of D. Schwarz, Heap,
