- W4310637033 abstract "G-algebras, or Groebner bases algebras, were considered by Levandovsky, these algebras include very important families of algebras, like the Weyl algebras and the universal enveloping algebra of a finite dimensional Lie algebra. These algebras are not graded in a natural way, but they are filtered. Going to the associated graded algebra is the standard way to study their properties. In a previous paper we studied an homogeneous version of the G-algebras, which results naturally graded, and through a des homogenization property, we obtain an ordinary G-algebra. The main results in our first paper were the following: Homogeneous G-algebras are Koszul of finite global dimension, Artin Schelter regular, noetherian and have a Poincare Birkoff basis. We give the structure of their Yoneda algebras by generators and relations. In the second part of the paper we consider the quantum polynomial ring and prove, for the finitely generated graded modules, cohomology formulas analogous to those we have in the usual polynomial ring. In the third part we use the results of the previous part to study the cohomology of the homogeneous G-algebras. Part four was dedicated to the study of the relations between an homogeneous G-algebra B and its des homogenization B/(Z-1)B=A, Applications to the study of finite dimensional Lie algebras and Weyl algebras were given. In the last sections of the paper we study the relations, at the level of modules, among the homogenized algebra B, its graded localization B_{z}, the des homogenization A=B/(Z-1)B and the Yoneda algebra B^{!}. In this paper we investigate the relations among all these algebras at the level of derived categories." @default.
