活动简介

Modern mathematical research has been enriched by exploring the bijection between Higgs bundles and local systems over noncompact Riemann surfaces, an incredible feat accomplished profoundly by C. Simpson by introducing weighted filtrations. In this discussion, our focus will be on further unraveling this relationship by delving into the correlation between the Dolbeault and de Rham moduli spaces for generally complex reductive structure groups,with the language of parahoric group schemes as initially established by Bruhat-Tits. We further investigated how the Langlands duality come into play. This presentation is based on collaborative work with Georgios Kydonakis, Pengfei Huang, and Hao Sun.
