- Title
Classification of Equivariant Star Products on Symplectic Manifolds.
- Authors
Reichert, Thorsten; Waldmann, Stefan
- Abstract
In this note, we classify invariant star products with quantum momentum maps on symplectic manifolds by means of an equivariant characteristic class taking values in the equivariant cohomology. We establish a bijection between the equivalence classes and the formal series in the second equivariant cohomology, thereby giving a refined classification which takes into account the quantum momentum map as well.
