摘要
本文给出了Auslander-Gorenstein滤环上全律模(holonomicmodules)的一个特征簇刻划,由此得到了通过特征理想的极小素因子(有限个)计算余维数的公式。
In this paper,we give a characterization of holonomic modules over Auslander-Gorenstein filtered rings in terms of their characteristic varieties.Then,on the basis of the aboveresult, We establish a formula for computing the codimension by (finite number of)minimal primedivisors of the characteristic ideals.
