Bianchi Identities for Non-Geometric Fluxes - From Quasi-Poisson
Structures to Courant Algebroids    [PDF]

Ralph Blumenhagen, Andreas Deser, Erik Plauschinn, Felix Rennecke

Starting from a (non-associative) quasi-Poisson structure, the derivation of a Roytenberg-type algebra is presented. From the Jacobi identities of the latter, the most general form of Bianchi identities for fluxes (H,f,Q,R) is then derived. It is also explained how this approach is related to the mathematical theory of quasi-Lie and Courant algebroids.
