$\theta$-almost twisted Poisson cohomology

Differential Geometry 2025-09-12 v2

Abstract

We introduce the notion of a θ\theta-almost twisted Poisson structure on manifolds, which involves incorporating a closed 11-form θ\theta into twisted Poisson structures under specific conditions. We provide a characterization of this structure on low-dimensional manifolds and construct the Lie-Rinehart algebra on the module of 11-forms on manifolds equipped with this structure. This construction leads to a cochain complex and its associated cohomology, which we refer to as θ\theta-almost twisted Poisson cohomology. An example illustrating this cohomology is also presented on R5\mathbb{R}^5.
