The presymplectic form is a concept from differential geometry and mathematical physics, particularly in the study of Hamiltonian dynamics and the theory of differential forms. It generalizes the notion of a symplectic form, which is a closed, non-degenerate 2-form defined on an even-dimensional manifold. In more detail: 1. **Definition**: A presymplectic form on a smooth manifold \( M \) is a closed 2-form \( \omega \) (i.e.
