Massey products, sphere bundles and T-duality
Gil R. Cavalcanti
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 repacka…

T-duality for transgressive fibrations
Gil R. Cavalcanti
We extend the notion of topological T-duality from oriented sphere bundles to transgressive fibrations, a more general type fibration characterised by the abundance of transgressiv…

Topological Spherical T-duality -- Dimension change from higher degree -flux
Gil R. Cavalcanti, Bart Heemskerk, Bernardo Uribe
Topological Spherical T-duality was introduced by Bouwknegt, Evslin and Mathai in [BEM15] as an extension of topological T-duality from -bundles to -bundles en…
