On the homogenized Weyl Algebra

Abstract

The aim of this paper is to give relations between the category of finetely generated graded modules over the homogeneized Weyl algebra $B_n$, the finetely generated modules over the Weyl algebra $A_n$ and the finetely generated graded modules over the Yoneda algebra $B_n^{!}$ of $B_n$. We will give these relations both at the level of the categories of modules and at the level of the derived categories.
