Traces for star products on symplectic manifolds


We give a direct elementary proof of the existence of traces for arbitrary star products on a symplectic manifold. We follow the approach we used in [9], solving first the local problem. A normalisation introduced by Karabegov [10] makes the local solutions unique and allows them to be pieced together to solve the global problem. This research was partially… (More)
