Abstract
Let λi(n), i=1,2,3, denote the normalized Fourier coefficients of a holomorphic eigenform or Maass cusp form. In this paper we shall consider the sum: S:=[Formula presented]∑H≤h≤2HV([Formula presented])×∑N≤n≤2Nλ1(n)λ2(n+h)λ3(n+2h)W([Formula presented]), where V and W are smooth bump functions, supported on [1,2]. We shall prove a nontrivial upper bound, under the assumption that H≥N1/2+ϵ.
