%0 Journal Article %T Twisted L-functions over number fields and Hilbert's eleventh problem %A Valentin Blomer %A Gergely Harcos %J Mathematics %D 2009 %I arXiv %X We prove a Burgess-like subconvex bound for twisted L-functions of a fixed irreducible cuspidal automorphic representation of GL(2) over a totally real number field. The proof is based on a spectral decomposition of shifted convolution sums and a generalized Kuznetsov formula. %U http://arxiv.org/abs/0904.2429v3
