  Motivated by the quest to understand the analog of non-geometric flux
compactification in the context of M-theory, we study higher dimensional
analogs of generalized Poisson sigma models and corresponding dual string and
p-brane models. We find that higher generalizations of the algebraic structures
due to Dorfman, Roytenberg and Courant play an important role and establish
their relation to Nambu-Poisson structures.
