A variational principle for symplectic connections
Résumé
We introduce a variational principle for symplectic connections and study the corresponding field equations. For two-dimensional compact symplectic manifolds we determine all solutions of the field equations. For two-dimensional non-compact simply connected symplectic manifolds we give an essentially exhaustive list of solutions of the field equations. Finally we indicate how to construct from solutions of the field equations on $(M, \omega)$ solutions of the field equations on the cotangent bundle to M with its standard symplectic structure.
