Despite what I think is more than one supposed proof of RH by de Branges that was not accepted by the mathematical community, he is also known for proving the Bieberbach conjecture, a longstanding and important unsolved problem in complex function theory since 1916, in 1984. --Dan _____________________________________________________________________ "It don't mean a thing if it ain't got that certain je ne sais quoi." --Peter Schickele
