I've now dowloaded and quickly scanned this paper -- by one Xian-Jin Li of Brigham Young U. -- as well as one by Bombieri that the Li's proof of RH relies on. I am uniquely unqualified to read this paper in any detail, relying as it does on algebraic and analytic number theory as well as functional analysis. But superficially, it certainly has the aura of a serious attempt to prove RH (unlike papers of a certain other mathematician who will go unnamed). This could be very exciting! Then again, maybe not. --Dan _____________________________________________________________________ "It don't mean a thing if it ain't got that certain je ne sais quoi." --Peter Schickele
