Tóm tắt: The geometric Satake equivalence provides an equivalence between (equivariant) perverse sheaves on the affine Grassmannian of a given reductive group and the category of representations of its Langlands dual group. After the first complete proof due to Mirkovic-Vilonen, there are several approaches to the geometric Satake equivalence. In this talk, I will present to the audience two motivic enhancements of the geometric Satake: the one by Richarz-Scholbach using mixed Tate motives and the one by the speaker using perverse Nori motives.
