Department of Mathematics - Algebra and Geometry Seminar - Torsors on loop groups

For various applications in geometric representation theory, such as affine Springer theory or the more recent Ben-Zvi--Sakellaridis--Venkatesh program, it has become necessary to develop a set of foundational results on loop space and torsors on loop groups. We will survey different techniques on them and explain how they can be applied to explicit situations.
