Thanks to work of Toen, one has powerful and efficient framework to define the Hochschild (co)homology of dg- categories. However, to compute these invariants, one must often replace a dg-category of bi-modules with a quasi- equivalent category that is more tied to geometry. In this talk, we will discuss how to do this for categories of singularities of graded complete intersections.
