T-duality for principal torus bundles
Peter Bouwknegt, Keith Hannabuss, Varghese Mathai
In this paper we study T-duality for principal torus bundles with H-flux. We identify a subset of fluxes which are T-dualizable, and compute both the dual torus bundle as well as t…
On the Topology and Flux of T-Dual Manifolds
Peter Bouwknegt, Jarah Evslin, Varghese Mathai
We present a general formula for the topology and H-flux of the T-dual of a type two compactification. Our results apply to T-dualities with respect to any free circle action. In p…
Type I D-branes in an H-flux and twisted KO-theory
V. Mathai, M. K. Murray, D. Stevenson
Witten has argued that charges of Type I D-branes in the presence of an H-flux, take values in twisted KO-theory. We begin with the study of real bundle gerbes and their holonomy.…
