Divisor moments of polynomials in Fourier coefficients of modular forms
Wonwoong Lee
We study higher moments of the divisor function evaluated at polynomial expressions in the Fourier coefficients of a non-CM newform. The logarithmic exponent appearing in our estim…

Moment of derivatives of L-functions for two distinct newforms
Seokhyun Choi, Beomho Kim, Hansol Kim +2
We establish an unconditional result concerning the asymptotic formula for the moment of derivatives of -functions over quadrati…
