dc.descriptionWe prove that the maximal number of directed edges in a vertex-critical strongly connected simple digraph on n vertices is n(n-1)/2 - n +4.
dc.description5 pages, no figures, given at the Eleventh Haifa Matrix Theory Conference 26.5.1999 Accepted at Discrete Math. v1 is the submitted version, v2 is the version after the referee's corrections. Note the main correction: the result for edge critical strongly connected graphs is already known
