The Prym-Hitchin Connection and Anti-Invariant Level-Rank Duality

Algebraic Geometry 2025-12-18 v2

Abstract

We construct a "Hitchin-type" connection on bundles of non-abelian theta functions on higher-rank Prym varieties, for unramified double covers of curves. We formulate a version of level-rank duality in this Prym setting (building on work of Zelaci), show it holds for level one, and establish that the duality respects the flat connections at all levels.
