Seminar on Algebra, Geometry and Physics The standard ways of computing, or indeed defining, invariants of singular varietis use the procedure of resolution of singularities. To explicitly know a resolution, however, requires a good understanding of the singularities of the variety in question.
I will talk about methods that can be applied to the study of singular varieties without resolution of singularities, which originate from localization theorems in topology. As an example, I will present some computations involving the torus-equivariant cohomology of the (refined) Hilbert scheme of points on the plane.
