The Poisson enveloping algebra and the algebra of Poisson differential operators of a generalized Weyl Poisson algebra

Abstract

For a generalized Weyl Poisson algebra $A$, explicit sets of generators and defining relations are presented for its Poisson enveloping algebra $\CU (A)$. Simplicity criteria are given for the algebra $\CU (A)$ and algebra of Poisson differential operators $P\CD (A)$ on $A$. The Gelfand-Kirillov dimensions of the algebras $\CU (A)$ and $P\CD (A)$ are calculated. It is proven that the algebra $\CU (A)$ is a domain provided that the coefficient ring $D$ of the generalized Weyl Poisson algebra $A$ is a domain of essentially finite type over a perfect field. For the algebra $A$, the set of its minimal primes and the prime radical are described and an equidimensionality criterion is given. For the equidimensional algebra $A$ of essentially finite type, two regularity criteria are presented.
