地点：数学楼102报告厅
主讲人：左康 教授（武汉大学）
主持人：张通 教授
讲座内容简介：
In this short course I shall explain the recent joint work with Jinbang Yang in detail. Introduction to non-abelian p-adic Hodge theory, Higgs de Rham flow, p-adic Simpson correspondence for periodic Higgs bundles, Deligne’s p to l companions, Yu’s work on numerical characteristic p Simpson correspondence, Drinfeld’s work on Langlands correspondence for rank two l-adic local systems with cusps, Grothendieck-Messing deformation theorem for log abelian schemes. As an application we construct all rank-2 motivic local systems over the complex projective line with 4 punctures with given type of local monodromy: unipotent around {0, 1, λ} and quasi unipotent around infinity with eigenvalues {-1, -1}. It is remarkable, recently Lam-Litt provided a totally different approach to the above by using Katz middle convolution.
