报告简介：

Let π be a cuspidal automorphic representation of GL_2(A_Q) with trivial central character, deined by a non-CM holomorphic newform of weight k ≥ 2 and level N. In this talk, we present recent results on sums of Hecke eigenvalues attached to symmetric power lifts of π. By employing the quantitative Sato-Tate theorem, we sharpen the upper bounds due to Chiriac and Yang for sums over values of monic irreducible polynomials. Moreover, we derive asymptotic formulae for sums over monomials. This is joint work with Shu Luo.
