Moduli Spaces of Filtered G-local Systems on Curves

Algebraic Geometry 2025-07-08 v3

Abstract

In this paper, we construct the moduli spaces of filtered GG-local systems on curves for an arbitrary reductive group GG over an algebraically closed field of characteristic zero. This provides an algebraic construction for the Betti moduli spaces in the tame nonabelian Hodge correspondence for vector bundles/principal bundles on noncompact curves. As a direct application, the tame nonabelian Hodge correspondence on noncompact curves holds not only for the relevant categories, but also for the moduli spaces.
