我们描述了Macaulay2包MixedHodgeModules,该包计算多项式环S在非常数约化多项式f处的局部化S_f上的Hodge滤过与权重滤过,以及扭曲局部化S_f f^{-\alpha}上的相应滤过,其中\alpha\in QQ为有理数。该包包含计算Hodge理想、加权Hodge理想、高阶乘子理想、Hodge滤过的生成级别、元素的权重级别、p-函数以及权重滤过长度的功能。它还提供了计算超曲面的分次de Rham复形、Du Bois复形和交Du Bois复形的例程。
英文摘要
We describe the Macaulay2 package MixedHodgeModules, which computes Hodge and weight filtrations on localizations S_f of a polynomial ring S at a non-constant reduced polynomial f, as well as on twisted localizations S_f f^{-α}, where α\in QQ is rational. The package includes functionality for computing Hodge ideals, weighted Hodge ideals, higher multiplier ideals, generation levels of Hodge filtrations, weight levels of elements, p-functions, and lengths of weight filtrations. It also provides routines for computing graded de Rham complexes, Du Bois complexes, and intersection Du Bois complexes of hypersurfaces.
