Abstract
Let π be a cuspidal representation on GL(2,A_Q) We give nontrivial lower and upper bounds for average of absolute values of Dirichlet coefficients associated to π; and nontrivial upper bound in the case of Sym^kπ, k= 2,3. These bounds generalize the known estimates in holomorphic case to Maass forms, without assuming the Ramanujan–Petersson conjecture.
