N2 - Let q≥2 and N≥1 be integers. W.Zhang recently proved that for any fixed ε>0 and qε≤N≤q1/2-ε, \[ ∑ χ ≠ χ 0} ∑ Nn=1 χ (n)2 |L(1, χ )|2 = (1 + o(1)) αq q N, where the sum is taken over all nonprincipal characters modulo q, L(1,) denotes the L-functions corresponding to χ, and αq=qo(1) is some explicit function of q. Here we improve this result and show that the same asymptotic formula holds in the essentially full range qNq1.
