Stokes structure of mild difference modules

Algebraic Geometry 2026-04-21 v2 Complex Variables

Abstract

We introduce a category of filtered sheaves on a circle to describe the Stokes phenomenon of linear difference equations with mild singularity. The main result is a mild difference analog of the Riemann-Hilbert correspondence for germs of meromorphic connections in one complex variable by Deligne-Malgrange.
