We review the AKSZ construction as applied to the topological open membranes and Poisson sigma models. We describe a generalization to open topological p-branes and Nambu-Poisson sigma models.
In this paper we construct Cech cohomology groups that form a Gysin-type long exact sequence for principal torus bundles. This sequence is modeled on a de Rham cohomology sequence published in earlier work by Bouwknegt, Hannabuss and Mathai, which wa s developed to compute the global properties of T-duality in the presence of NS H-Flux.
In this paper we construct a Chern-Weil isomorphism for the equivariant Brauer group of R^n-actions on a principal torus bundle, where the target for this isomorphism is a dimensionally reduced Cech cohomology group. From this point of view, the usua l forgetful functor takes the form of a connecting homomorphism in a long exact sequence in dimensionally reduced cohomology.
In this paper we outline a recent construction of a Chern-Weil isomorphism for the equivariant Brauer group of $mathbb R^n$ actions on a principal torus bundle, where the target for this isomorphism is a dimensionally reduced vCech cohomology group. Using this latter group, we demonstrate how to extend the induced algebra construction to algebras with a non-trivial bundle as their spectrum.
