Abstract

Luo has proven an optimal upper bound for the L4L^4-norm of dihedral Maass forms of large eigenvalue, by bounding a mean value of triple product LL-functions. Motivated by this result, we study a mean value of LL-functions having similar shape, and obtain for it an asymptotic with power savings. Our work may be helpful in eventually obtaining an asymptotic for the L4L^4-norm.
