Query: Noetherian Skew Inverse Power Series Rings   We study skew inverse power series extensions R[[y^{-1};tau,delta]], where R
is a noetherian ring equipped with an automorphism tau and a tau-derivation
delta. We find that these extensions share many of the well known features of
commutative power series rings. As an application of our analysis, we see that
the iterated skew inverse power series rings corresponding to nth Weyl algebras
are complete local, noetherian, Auslander regular domains whose right Krull
dimension, global dimension, and classical Krull dimension, are all equal to
2n.
