On digraphs with no two disjoint directed cycles

We obtain a result on configurations in 2-connected digraphs with no two disjoint dicycles. We derive various consequences, for example a short proof of the characterization of the minimal digraphs having no vertex meeting all dicycles and a polynomially bounded algorithm for finding a dicycle through any pair of prescribed arcs in a digraph with no two disjoint dicycles, a problem which is NP-complete for digraphs in general.
