The primitive factors of the enveloping algebra U (sl (2, C) are classified up to Morita
equivalence using the Hattori-Stallings map. Let U= U (sl (2, C)) be the enveloping algebra …

This article is a survey of some aspects of the K-theory of Noetherian rings. Mainly we shall
be concerned with calculating the (Quillen) K-groups for specific Noetherian rings but we …

Let S= kA denote the group algebra of a finitely generated free abelian group A over the field
k and let G be a finite subgroup of GL (A). Then G acts on S by means of the unique …

In the case of a (vonNeumann) unit-regular ring R and a finite subgroup G of automorphisms
of R with IGI-'ER, Kado has given in [Kl] and [K2], relations between the pseudo-rank …

K. Goodearl [Gl] considered the State Space, St (R), of a noetherian ring R; and, in joint work
with RB Warfield [GW], described the structure of the sate space of commutative rings …

We investigate the Grothendieck group G0 (R) of finitely generated modules over the ring of
invariants R= SG of the action of a finite group G on an FBN ring S under the assumption that …

In this thesis, we are concerned with the question of when a skew group ring of a finite group
over a prime Noetherian ring is a maximal order. Contrary to what one might first expect, it is …

We describe the ring of global differential operators over a singular, rational, projective curve
over an algebraically closed field of characteristic zero. For a affine curves, it is well-known …

The Grothendieck group of the ring of invariants R of a finite group acting linearly in coprime
characteristic on the symmetric algebra S= S (V) is investigated. It is shown that where F is a …
