| Abstract: | Let D be a strongly connected digraph with order n,A(D) be a adjacency matrix of D.Then A (D) A2 (D) is a primitive matrix. The exponent of A(D) A2 (D) is called 2 order exponent of D. In this paper,the 2 order exponent set of strongly connected digraph with order n is determined completely, S(2 ,n)={1,2,...,n-1}. |
