Speaker: Dinesh Valluri (Western) Title: "Introduction to equivariant Chow groups" Room: MC 105C Abstract: We will recall the notion of Chow group of a scheme briefly and motivate the need for the notion of Equivariant Chow groups. We give a definition of the latter which closely resembles the Borel construction of Equivariant Cohomology groups via certain approximation of the universal G-bundle. We will prove that such construction is well defined and see some examples. We will end the talk with a discussion of functoriality of flat pullbacks and proper pushforwards in the equivariant context. |
