| Abstract: | Let RD( n,i ) be the set of all digraphs of order n with i ministrong components, and NR( n,i)={k| there exists a digraph D with n vertices and i ministrong components such that k(D)=k}. let NE n be the set of all primitive ministrong digraphs. We obtain an explicit formula for the set NR(n,i) of indices of convergence for digraphs with n vertices and iministrong components. |
