本文研究一维环面上的协变模的微分算子环。特别是,我们分析时,他们是森田等价的,当他们是简单的,当他们有有限的整体尺寸。作为一个副结果,我们得到了Bernstein-Beilinson等价到加权射影空间的一个推广。
In this paper we study rings of differential operators for modules of covariants for one-dimensional tori. In particular we analyze when they are Morita equivalent, when they are simple, and when they have finite global dimension. As a side result we obtain an extension of the Bernstein-Beilinson equivalence to weighted projective spaces.
