We define the notion of a PERFECT Dixmier algebra for M and show how this produces a graded (non-local) equivariant star product on M with several very nice properties. This is part of a larger program we have been developing for working out the orbit method for nilpotent orbits.8 pages; Latex; see http://www.math.psu.edu/rkb for more papersQuantum AlgebraRepresentation Theory22E46, 17B35, 53D55text
