Almost symplectic manifold

From Wikipedia, the free encyclopedia

In differential geometry, an almost symplectic structure on a differentiable manifold M is a two-form ω on M that is everywhere non-singular.[1] If, in addition, ω is closed, then it is a symplectic form.

An almost symplectic manifold is an Sp-structure; requiring ω to be closed is an integrability condition.
