| Aug 29, 2012 at 9:22 | comment | added | Felix Goldberg | Thanks, Dennis, that's a really beautiful one. (Looks a bit like a modular formula to me, but probably it's just my weird mathsight). Do you know perhaps of a useful way to reduce the non-Hermitian case the Hermitian that might help out here? | |
