Abstract

Using the second moment of Dirichlet 𝐿-functions on the critical line over the major arcs M(L𝑏), with 𝜏 = 𝑦3𝑥−1L−𝑏1 , and excluding a small neighborhood of the centers of these arcs, i.e., those 𝛼 satisfying |𝛼 − 𝑎
𝑞 | > (8𝜋𝑦2)−1, for 𝑦 ⩾ 𝑥^1− 1/(9−4√2)L𝑐2 , where 𝑐2 = 2𝐴+24+(√2−1)𝑏1/2√2−1, we obtain the estimate

Moreover, in a small neighborhood of the center of the major arcs, defined by |𝛼−𝑎𝑞 | ⩽ (8𝜋𝑦2)−1,for 𝑦 ⩾ 𝑥^5/8 L1,5𝐴+0,25𝑏+18, an asymptotic formula with a remainder term is obtained for 𝑆2(𝛼; 𝑥, 𝑦), where 𝐴, 𝑏1, and 𝑏 are arbitrary fixed positive constants, and L = ln 𝑥.
