Title:

**Higgs-de Rham flow in the non-abelian p-adic Hodge theory and a p-adic analogue of the uniformization theory of a hyperbolic Riemann surface **

Abstract:

The notion " Higgs-de Rham flow" over schemes X/W(k) over the ring of Witt vectors of
finite field k of characteristic p introduced in a recent paper by Lan-Sheng-Zuo has found some interesting applications in arithmetic geometry. Higgs-de Rham flow induces a correspondence between semistable graded Higgs bundles with $c_i=0$ and crystalline representations of the algebraic fundamental group of the generic fibre of $X,$ an p-adic analogue of the well known correspondence between polystable graded Higgs bundles of $c_i=0$ and polarized complex variation of Hodge structures. In my lecture I shall talk about application of Higgs-de Rham flow on uniformization of hyperbolic p-adic curves, which is closely related to S. Mochizuki's p-adic Teichmueller thoery. This is a joint work with Lan-Sheng-Yang.
