Weak-Hamiltonian dynamical systems
A big-isotropic structure E is an isotropic subbundle of TM⊕T*M, endowed with the metric defined by pairing. The structure E is said to be integrable if the Courant bracket [X,Y]∊ΓE, ∀X,Y∊ΓE. Then, necessarily, one also has [X,Z]∊ΓE⊥, ∀Z∊ΓE⊥ [Vaisman, I., “Isotropic subbundles of TM⊕T*M,” Int. J. Geom. Methods Mod. Phys. …
