Moduli spaces of Lambda-modules on abelian varieties

We study the moduli space M-x (Lambda, n) of semistable Lambda-modules of vanishing Chern classes over an abelian variety X, where A belongs to a certain subclass of D-algebras. In particular, for Lambda = D-X (resp. A = Sym(center dot)TX) we obtain a description of the moduli spaces of flat connections (resp. Higgs bundles). We give a description of M-x (Lambda, n) in terms of a symmetric product of a certain fibre bundle over the dual abelian variety (X) over cap. We also give a moduli interpretation to the associated Hilbert scheme as the classifying space of Lambda-modules with extra structure. Finally, we study the non-abelian Hodge theory associated to these new moduli spaces. (C) 2017 Elsevier Inc. All rights reserved. (AU)
