Nonvanishing of Second Coefficients of Hecke Polynomials on the Newspace

William Cason, Akash Jim, Charlie Medlock +3

For $m \geq 1$ , let $N \geq 1$ be coprime to $m$ , $k \geq 2$ , and $I ¨ $ be a Dirichlet character modulo $N$ with $I ¨ (- 1) = (- 1)^{k}$ . Then let $T_{m}^{new} (N, k, I ¨ )$ denote the rest…

On the average size of the eigenvalues of the Hecke operators

William Cason, Akash Jim, Charlie Medlock +2

We determine the average size of the eigenvalues of the Hecke operators acting on the cuspidal modular forms space $S_{k} (I^_{0} (N))$ in both the vertical and the horizontal perspectiv…
