Algebraic Geometry 2021-01-08 v1

Abstract

Let (X,D)(X,D) and (X,D)(X',D') be two compact Riemann surfaces of genus g4g \geq 4 with the set of marked points DXD \subset X and DXD' \subset X'. Fix a parabolic line bundle LL with trivial parabolic structure. Let NSp(2m,α,L)\mathcal{N}_{\textnormal{Sp}}(2m,\alpha,L) and NSp(2m,α,L)\mathcal{N}'_{\textnormal{Sp}}(2m,\alpha,L) be the moduli spaces of stable symplectic parabolic Higgs bundles over XX and XX' respectively, with rank 2m2m and fixed parabolic structure α\alpha, with the symplectic form taking values in LL. We prove that if NSp(2m,α,L)\mathcal{N}_{\textnormal{Sp}}(2m,\alpha,L) is isomorphic to NSp(2m,α,L)\mathcal{N}'_{\textnormal{Sp}}(2m,\alpha,L), then there exist an isomorphism between XX and XX' sending DD to DD'.
