Covariant Star Product for Exterior Differential Forms on Symplectic Manifolds

After a brief description of the Z-graded differential Poisson algebra, we Introduce a covariant star product for exterior differential forms and give an explicit expression for it up to second order in the deformation parameter h, in the case of symplectic manifolds. The graded differential Poisson algebra endows the manifold with a connection, not necessarily torsion-free, and places upon the connection various constraints
