Abstract

Following Friedlander & Iwaniec [FRIEDLANDER, J. B.—IWANIEC, H.: Summation formulae for coefficients of L-functions, Canad. J. Math. 57 (2005), 494—505], the objective of this note are the coefficients an of the Dirichlet series for L(s, χ1)L(s, χ2)L(s, χ3) where χ1, χ2, χ3 are primitive Dirichlet characters with modules D1, D2, D3. For ∑n≤xan, with x large, sharp asymptotics are established which are uniform in D1, D2, D3. To this end, the modern method for the estimation of exponential sums, due to [HUXLEY, M. N.: Area, Lattice Points, and Exponential Sums, LMS Monographs, New Ser. 13, University Press, Oxford, 1996] and others, is applied with gain.
