"Discrete Mean Values of Dirichlet *L*-functions"

Let χ be a Dirichlet character modulo a prime number *p* ⩾ 3 and let \mathfrak *a*_χ:=(1-χ(-1))/2. Define the mean value

\begin{align*}

\mathcal{M}_{p}(s,\chi):=\frac{2}{p-1}\sum_{\substack{\psi \bmod p\\\psi(-1)=-1}}L(1,\psi)L(s,\chi\overline{\psi})

\end{align*}

for a complex number *s* such that *s*≠ 1 if \mathfrak a _χ=1.
