Dimension variation of Gouvêa-Mazur type for Drinfeld cuspforms of level ${\Gamma }_1(t)$

Shin Hattori

Let $p$ be a rational prime and $q>1$ a $p$-power. Let $S_k({\Gamma }_1(t))$ be the space of Drinfeld cuspforms of level ${\Gamma }_1(t)$ and weight $k$ for ${\mathbb{F}}_q[t]$. For any non-negative…
