Hecke structure of spaces of half-integral weight cusp forms
We investigate the connection between integral weight and half-integral weight modular forms. Building on results of Ueda [14], we obtain structure theorems for spaces of half-integral weight cusp forms S k/2 (4N ,χ ) where k and N are odd nonnegative integers with k ≥ 3, and χ is an …
