摘要：
Let pi be a SL(3, Z) Hecke-Maass cusp form, fbe a SL(2, Z) holomorphic cusp form or Maass cusp form and chi be any nontrivial character mod p, where pis prime. We show that the L-functionassociated with this triplet satisfy L(1/2, pi x f x chi) << pi,f,epsilon p(3/2) (- 1/16 +) (epsilon). The method also yields the subconvex bound L(1/2, pi circle times chi) << pi,epsilon p(3/4) (- 1/32 +) (epsilon). (c) 2022 Elsevier Inc. All rights reserved.
