   4. (November 8th) Cheuk Yu Mak - Loop group action on symplectic cohomology. Abstract: For a compact Lie group G, its massless Coulomb branch algebra is the G-equivariant Borel-Moore homology of its based loop space. This algebra is the same as the algebra of regular functions on the BFM space. In this talk, we will first describe this algebra. Then I will give an idea of how it acts on the equivariant symplectic cohomology. Finally, we also explain how it relates to the Coulomb branch algebra of cotangent-type representations. This is joint work with Eduardo González and Dan Pomerleano. 

   5. (November 15th) Mattew Spong - Equivariant elliptic cohomology and the 2-loop groupoid. Abstract: Elliptic cohomology is a type of cohomology theory associated with elliptic curves that first appeared in the late 1980s. The first equivariant version of elliptic cohomology was given in 1994 by Grojnowski in the complex-analytic setting. This "delocalised" theory was built in an ad hoc way using ordinary Borel cohomology for certain applications in representation theory. Recently, there has emerged a much more conceptual picture of Grojnowski's theory whereby its relationship to loop groups has been made clear. In this talk I plan to describe this picture and possibly sketch some future directions.
