On the geometric quantization of $θ$-almost twisted Poisson manifold

Abstract

We introduce and investigate the concept of a $θ$-almost twisted Poisson manifold $(M,Λ,φ,θ)$. This structure consists of a smooth manifold $M$ equipped with a bivector field $Λ$, a 3-form $φ$, and a closed 1-form $θ$, satisfying the following conditions: the exterior derivative $dφ$ of $φ$ equals the wedge product $θ\wedge φ$; the anchor $Λ^\#(θ)$ of $θ$ vanishes identically; and one-half of the Schouten-Nijenhuis bracket $[Λ, Λ]$ equals the anchor $Λ^\#(φ)$ of $φ$. This structure generalizes both Poisson and twisted Poisson manifolds, permitting the 3-form $φ$ to be non-closed in a way controlled by the 1-form $θ$. We construct a Lie-Rinehart algebra on the module of 1-forms $Ω^1(M)$, giving rise to a cochain complex and an associated cohomology theory called $θ$-almost twisted Poisson cohomology. Moreover, we develop the geometric quantization of these manifolds by defining a suitable contravariant derivative, establishing a prequantization condition in terms of the cohomology, and constructing a quantum Hilbert space via polarization. We illustrate our results with several examples, including the computation of the cohomology and quantization on $\mathbb{R}^5$.
