In an earlier posting of a problem I had a mistake in one of the results. This is a reposting to correct the mistake. Let Z be a positive integer. Let M = Z/2 if Z is...

The Riemann Hypothesis says that pi(n)=Li(n)+O(sqrt(n)log n). If it were true, is it known if it would follow that O(sqrt(n) log n) is the best bound for pi(n)-Li(n)?...

Is there a classification of the hypergeometric functions with real parameters that have no complex zeros? thanks, Steve

I said: (1) As far as I know, the best explicit bound on the number of S-integers on an elliptic curve over Q is that of Hajdu and Herendi (MR1615334). Is there a similar...
