Klingen Vectors for Depth Zero Supercuspidals of $GSp(4)$

Abstract: Let $F$ be a non-archimedean local field of characteristic zero and $(\pi, V)$ a depth zero, irreducible, supercuspidal representation of $GSp(4, F)$. We calculate the dimensions of the spaces of Klingen-invariant vectors in $V$ of level $\mathfrak{p}^n$ for all $n\geq 0 $.
