On the Existence and Properties of Left Invariant -Symplectic Structures on Lie Groups with Bi-Invariant Pseudo-Riemannian Metric
Ilham Ait Brik, Mohamed Boucetta
-symplectic manifolds are a convenient framework to study classical field theories and they are a generalization of polarized symplectic manifolds. This paper focus on the exist…
