几何D-模的过滤限制

Filtered restriction of geometric D-modules

Rémi Arcadias

摘要:

在D-模理论中,我们有模沿着光滑簇的限制的概念。T. Oaku和N. Takayama描述了一个计算限制的过程,该过程从适应于Kashiwara-Malgrange的V-过滤的自由分解开始。利用适用于(阶和V)-双滤的自由分解理论(T. Oaku,N. Takayama和M. Granger),我们赋予该限制一个序过滤,并证明了Oaku和Takayama的过程遵守序过滤。因此,我们计算的代数局部上同调模的最小表示与一个准齐次多项式与孤立奇点,被视为D-模,并赋予一种极点阶过滤。

英文摘要:

In D-module theory, we have the notion of the restriction of a module along a smooth variety. T. Oaku and N. Takayama have described a process to compute the restriction, which starts from a free resolution adapted to the V-filtration of Kashiwara-Malgrange. By using the theory of free resolutions adapted to the (order and V)-bifiltration (from T. Oaku , N. Takayama and M. Granger), we endow the restriction with an order filtration and we show that the process of Oaku and Takayama respects the order filtration. In consequence, we compute a minimal presentation of the algebraic local cohomology module associated with a quasi-homogeneous polynomial with an isolated singularity, viewed as a D-module and endowed with a kind of a pole order filtration.
