Equivariant Cohomology and Localization after Anton Alekseev
Yıldıray Ozan
ODTÜ, Turkey
Özet : We will try to present the notes by Anton Alekseev on Equivariant Localization, mainly focusing on $S^1$-actions. First, we will introduce Stationary Phase Method. Then we will define equivariant $S^1$-cohomology and present a proof of the localization theorem suggested by E. Witten. If time permits, finally we will end by the Duistermaat-Heckman formula and its proof.
