Alladi Ramakrishnan Hall

Spherical T-duality and M-geometry

Prof. Peter Bouwknegt

Australian National University

T-duality is an equivalence of String Theories on manifolds which
are circle (or more generally, torus) bundles equipped with a background
flux. Mathematically it provides an isomorphism for twisted
cohomology and K-theory for these manifolds. In this talk I will briefly
review T-duality for circle bundles, and then discuss a recent generalisation
to 3-sphere bundles, as well as the associated (generalised) geometry.
This talk is based on joint work with Jarah Evslin and Mathai Varghese
