Observables and Symmetries of n Plectic Manifolds Leonid Ryvkin gives a motivated and self sustained introduction to n plectic geometry with a special focus on symmetries. The relevant algebraic structures from scratch are developed. The author generalizes known symplectic notions notably observables and symmetries to the n plectic case culminating in solving the existence question for co moment maps for general pre n plectic manifolds. Finally partial results scattered along the literature are derived from our general result.
