Abstract：
I will discuss recent joint work with Adeel Khan in which we construct a very general framework for (equivariant) elliptic cohomology, an exotic cohomology theory valued in sheaves on spaces of bundles on elliptic curves. I will review the classical (rational and trigonometric analogues) before sketching the elliptic story. Time permitting I will sketch a non-commutative version of the story, which is joint work in progress with Scherotzke, Sibilla and Tomasini.
