On Modular Signs Of Half Integral Weights
Bin Chen, Jie Wu, Yichao Zhang
In this paper, we consider the first negative eigenvalue of eigenforms of half-integral weight k + 1/2 and obtain an almost type bound.

Non-vanishing and sign changes of Hecke eigenvalues for half-integral weight cusp forms
Bin Chen, Jie Wu
In this paper, we consider three problems about signs of the Fourier coefficients of a cusp form with half-integral weight:\begin{itemize}\item[--]The first negative…
