Aug 19, 2019 at 17:28 | comment | added | Jared Weinstein | Thanks so much for this answer, and for the clear explanation using vector bundles, especially the explanation of the constant term map. In the Deligne-Flicker paper you cite, Prop. 7.1 seems to be saying that for $\mathrm{deg} D = 4$, the number of cusp forms is $q$ on the nose, is that correct? | |
