摘 要: Classical Teichmiller space connects the geometry of hyperbolic surfaces with discrete and faithful representations of surface groups into PSL(2,R). Higher Teichmiller theory extends this viewpoint to higher-rank Lie groups. The non-abelian Hodge correspondence provides a complex-geometric description of surface group representations in terms of Higgs bundles, with harmonic maps forming a bridge between the two sides. In this talk, I will introduce the main ideas of the correspondence and explain its role in higher Teichmuiller theory, using Hitchin components as a guiding example. I will then discuss a natural but subtle question: how can we tell from a Higgs bundle whether the corresponding representation is discrete and faithful? This will illustrate both what the correspondence reveals and what remains difficult to see on the Higgs bundle side.
