| Abstract: |
Elliptic Hochschild homology is a novel invariant introduced by Moulinos—Robalo—Toen for affine derived schemes. I will explain how this invariant can be extended to quotient stacks of smooth varieties. In the complex case, a Tate construction recovers the complexified equivariant elliptic cohomology of the analytification of the original variety. Joint with various subsets of Sarah Scherotzke and Nicolò Sibilla.
