KAH2 - K-theory, algebraic cycles and motivic homotopy theory The classical Atiyah-Bott localization theorem relates the equivariant cohomology of a space X with the action of a torus T with the cohomology of its fixed locus after inverting finitely many elements in the cohomology of BT. This theorem finds applications in enumerative geometry when the parameter space has a natural torus action. The need to access more general parameter spaces (singular and stacky) and the need for refined counts (in other cohomology theories) motivates the need for a more general localization theorem. In this talk, based on a joint work in progress with Dhyan Aranha, Adeel Khan, Alexei Latyntsev and Hyeonjun Park, we will discuss such a unified Atiyah-Bott localization theorem for equivariant cohomology theories of possibly singular algebraic stacks with an action of a linear algebraic group.
