摘要：
Equivariant cohomology theories capture both the topology of space and the group action on it. The Borel equivariant cohomology is introduced in the realm of algebraic topology. The Weil model and Cartan model on smooth manifolds with group actions realize the Borel cohomology via differential geometric data. In this talk, I will describe certain super geometry and gauged super QFTs, which give us the Weil model and Cartan model as well as other geometric concepts such as equivariant curvature and equivariant Chern character, and therefore figure out certain physics related these equivariant objects. This represents our joint works with Stolz, Teichner, Schommer-Pries and Berwick -Evans.
