| Aug 7, 2019 at 8:31 | comment | added | David Loeffler | Assertions (3) and (4) are both false. There is a character modulo 7 for which $Q(\chi_q) = 0$. Even if you weaken the assertion a non-strict inequality $\ge 0$ rather than $> 0$, you can find characters of modulus $\le 20$ for which (3) and (4) are negative. Did you do any checking at all before you posted this conjecture here? | |

The title is improved.

changed Dirichlet polynomial to a sum involving Dirichlet character
