Local vanishing density of order $1$ and Divisor moments
Abstract
We establish a general framework relating local vanishing densities of order $1$ to logarithmic growth of divisor moments on regular arithmetic curves. As applications, we recover classical divisor moment estimates for polynomial values and establish their function field analogue. Furthermore, under GRH, we obtain a result on divisor moments for polynomials in the Fourier coefficients of non-CM cuspidal eigenforms with trivial nebentypus and trivial inner twist. The Fourier coefficients need not be integers, and the polynomials need not be squarefree. Under additional analytic hypotheses, we also allow a Sato--Tate angle restriction.
