Massey products, sphere bundles and T-duality

Abstract

We study spherical T-duality for iterated sphere bundles. We show that for a class of iterated sphere bundles the cohomological data contained in its Gysin sequences can be repackaged into data for a vanishing Massey product. We further show that if these bundles are endowed with an integral cohomology class of transgressive degree one, then they have a T-dual iterated sphere bundle, namely, the one associated to the same Massey product read backwards.

arXiv commentCorrected example regarding nodal fiber. Added a section on T-duality beyond iterated sphere bundles
