| Mar 11, 2012 at 18:58 | comment | added | Andrés E. Caicedo | @Noam: Looking at Grosswald's paper from 1963, what he uses is a weak version of Extended Riemann. The reference Barry Cipra mentioned and some of the papers they cite indicate the issue is exactly what you indicate. | |

| Mar 11, 2012 at 17:57 | comment | added | Barry Cipra | Googling on the title of the Grosswald paper produced a link to math.uab.edu/~simanyi/Goswick_et_al_final.pdf which (backing up the url to the ~simanyi) indicates it's a recent paper in JNT. | |
| Mar 11, 2012 at 17:08 | comment | added | Noam D. Elkies | Is this assuming "just" Riemann or Extended Riemann (i.e. for quadratic Dirichlet characters)? I don't know the Grosswald paper, but it seems from the list that the question comes down to the existence of a large idoneal number under the further condition that it be a sum of two squares, and there's likely no way to exploit this additional assumption, so it probably remains open. | |
