Compatible 𝐸-Differential Forms on Lie Algebroids over (Pre-)Multisymplectic Manifolds

Abstract

We consider higher generalizations of both a (twisted) Poisson structure and the equivariant condition of a momentum map on a symplectic manifold. On a Lie algebroid over a (pre-)symplectic and (pre-)multisymplectic manifold, we introduce a Lie algebroid differential form called a compatible 𝐸-𝑛-form. This differential form satisfies a compatibility condition, which is consistent with both the Lie algebroid structure and the (pre-)(multi)symplectic structure. There are many interesting examples, such as a Poisson structure, a twisted Poisson structure, and a twisted 𝑅-Poisson structure for a pre-𝑛-plectic manifold. Moreover, momentum maps and momentum sections on symplectic manifolds, homotopy momentum maps and homotopy momentum sections on multisymplectic manifolds have this structure.
