Equivariant Cohomology in These lectures will discuss the equivariant cohomology of algebraic varieties, concentrating on the case where the group is a torus and the variety is a homogeneous space such as a Grassmannian or flag variety, or the variety is a toric variety. The equivariant viewpoint enriches the classical intersection theory of these algebraic varieties; conversely, the tools of algebraic variety simplify the study of equivariant cohomology. The first lecture will include definitions and basic properties of equivariant cohomology; deeper properties and the examples will be worked out in the other two lectures.
