Cohomology of the moduli of Higgs bundles via positive characteristic

Mark Andrea de Cataldo, Davesh Maulik, Junliang Shen +1

For any two degrees coprime to the rank, we construct a family of ring isomorphisms parameterized by GSp(2g) between the cohomology of the moduli spaces of stable Higgs bundles whi…

A Cohomological Non Abelian Hodge Theorem in Positive Characteristic

Mark Andrea A. de Cataldo, Siqing Zhang

We start with a curve over an algebraically closed ground field of positive characteristic $p > 0$ . By using specialization techniques, under suitable natural coprimality conditions,…

Projective Completion of Moduli of $t$ -Connections on Curves in Positive and Mixed Characteristic

Mark Andrea A. de Cataldo, Siqing Zhang

We generalize a compactification technique due to C. Simpson in the context of $G_{m}$ -actions over the ground field of complex numbers, to the case of a universally Japanes…
