Abstract

Summary: In these notes we construct a quantization functor, associating a Hilbert space $$\mathcal{H}(V )$$ to a finite dimensional symplectic vector space V over a finite field $${\mathbb{F}}_{q}$$ . As a result, we obtain a canonical model for the Weil representation of the symplectic group SpV . The main technical result is a proof of a stronger form of the Stone–von Neumann theorem for the Heisenberg group over $${\mathbb{F}}_{q}$$ . Our result answers, for the case of the Heisenberg group, a question of Kazhdan about the possible existence of a canonical Hilbert space attached to a coadjoint orbit of a general unipotent group over $${\mathbb{F}}_{q}$$ .
