Abstract: 
Let G be a reductive group over an algebraically closed field of positive characteristic. Let C be a smooth projective curve over k. In the talk, I will give a description of the moduli space of at Gbundles in terms of the moduli space of GHiggs bundles over the Frobenius twist of C. This description can be regarded as the nonabelian Hodge theory for curves in positive characteristic. If time permits, I will explain an application of this result to geometric Langlands correspondence. This is joint work with Xinwen Zhu.
