Brane space localization and genus-0 T-duality with -flux
Fei Han, Varghese Mathai
We construct a geometric theory on the brane space associated to a gerbe with connection on . Normalized logarithmic holonomy around the latitude circles…
Moduli Spaces of Connections and B-fields from T-duality with H-flux
Fei Han, Pedram Hekmati, Tsuyoshi Kato +1
We study the geometry of mixed fields, consisting of a connection and a -field on a principal circle bundle over a Riemann surface, from the perspective of gauge theory and T-du…
Latitudinal dependence of heat transport in turbulent geostrophic convection
Veeraraghavan Kannan, Varghese Mathai, Xiaojue Zhu
Latitudinal variations in turbulent heat flux play a key role in the thermal and magnetic evolution of rapidly rotating planets and stars. Although global spherical-shell simulatio…
Active biphasic heat transfer enhancement in vertical natural convection
Haoran Qi, Chaoben Zhao, Yaning Fan +3
Vertical natural convection (VC), often cannot meet the high heat transfer demands due to the inherent misalignment of the direction of buoyancy (vertical) with the direction of th…
Loop Hori Formulae for T-duality and Twisted Bismut-Chern Character
Fei Han, Varghese Mathai
The main purpose of this paper is to establish the loop space formulation of T-duality in the presence of background flux. In particular, we construct a loop space analogue of the…
Index and small bundle gerbes
Varghese Mathai, Richard B. Melrose
By a small bundle gerbe we mean a bundle gerbe in the sense of Murray defined on a smooth, finite-dimensional, fibre bundle over a manifold. We construct such gerbes over compact o…
