Intuition for symplectic groups

This is an outgrowth of an extended comment dealing with the superficial difference between symplectic and orthogonal rotations embedded in the question. I posit that the theory for symplectic groups …

Which tensor fields on a symplectic manifold are invariant under all Hamiltonian vector fields?

Any symplectic linear transformations in $T_xM$ is locally realizable as a Hamiltonian vector field, thus for questions 1 and 2, one can profitably use representation theory of the symplectic group. …

Classical mechanics motivation for poisson manifolds?

For many reasons and purposes, it is the Poisson bracket, not the symplectic form, that plays a primary role. Equations of motion and, more generally, the evolution of observables have an easy fo …
