Abstract
An asymptotic behavior of the sum
for X → ∞ is studied in the critical strip, where L(s, Xp) is the Dirichlet series with the quadratic character Xp modulo p, where p is a prime number; v=1 or 3. With the help of large seive estimates a formula for this sum is obtained with two asymptotic terms on the critical line of the variable s. As a corollary the asymptotic expansion of this sum at the point s=1/2 is presented. The asymptotic formula for the sum
, where d runs over discriminants of quadratic fields, is also obtained.
