Gravity theory on Poisson manifold with -flux

arXiv:1508.05706 · doi:10.1002/prop.201500049

Abstract

A novel gravity theory based on Poisson Generalized Geometry is investigated. A gravity theory on a Poisson manifold equipped with a Riemannian metric is constructed from a contravariant version of the Levi-Civita connection, which is based on the Lie algebroid of a Poisson manifold. Then, we show that in Poisson Generalized Geometry the -fluxes are consistently coupled with such a gravity. An -flux appears as a torsion of the corresponding connection in a similar way as an -flux which appears as a torsion of the connection for- mulated in the standard Generalized Geometry. We give an analogue of the Einstein-Hilbert action coupled with an -flux, and show that it is invariant under both -diffeomorphisms and -gauge transformations.
