Abstract

We denote by λ _f (n) the n-th normalized Fourier coefficient of primitive holomorphic cusp form of even integral weight k ≥ 2 for the full modular group SL(2,). In this paper, we prove asymptotic formulae for l-th power sums of two types related to the Fourier coefficient λ _f (n), which refines previous results.
