摘要：T-duality is an equivalence of two physical theories (quantum field theories or string theories) with different spacetime geometries. It originates from string theories, finds applications in condensed matter physics and has profound connections with topology/geometry. In this talk, I will first briefly review the elegant mathematical formulation of T-duality in an H-flux by Bouwknegt-Evslin-Mathai. Then I will describe our joint work with Mathai about developing exotic twisted /mathbb{T}-equivariant cohomology theories in order to enhance the T-duality by capturing the exchange of winding and momentum, a fundamental feature of T-duality.
