Abstract
In this talk, I will discuss T-duality with H-flux for sigma models, modeled on T-duality with H-flux for spacetime as studied in [BEM]. We define exotic twisted equivariant cohomology of free loop space and show that it localises to twisted cohomology of spacetime. Additionally, we will introduce the loop Hori map, which gives an isomorphism between the exotic twisted equivariant cohomology of the T-dual sigma models.
This presentation is based on ongoing joint work with Fei Han (NUS).
