在微分算子环上均匀化一个模,我们定义了一个适应于过滤的最小自由分辨率的概念。我们表明,可以应用修改的算法的La Scala和Stillman计算这样一个自由的决议。通过去均质化,可以获得原始模块的自由分辨率,该分辨率足够小以进行计算,例如其限制和积分。我们已经实现了我们的算法在计算机代数系统Kan,并给出了使用这种实现的例子。
Homogenizing a module over the ring of differential operators, we define the notion of a minimal free resolution that is adapted to a filtration. We show that one can apply a modification of the algorithm of La Scala and Stillman to compute such a free resolution. By dehomogenization, one gets a free resolution of the original module that is small enough to compute, e.g. its restriction and integration. We have implemented our algorithm in a computer algebra system Kan and give examples by using this implementation.
