摘要:

我们研究了托里安品种的交集上同调Hodge模的Hodge滤波。更具体地说,我们研究了该交集上同调Hodge模的渐进de Rham复形的上同调sheaves,并给出了其与交集上同调作为可构造复形的留数之间的精确公式。主要思想是利用Ishida复形来计算反射微分 sheaf 的更高直接像。

英文摘要:

We study the Hodge filtration of the intersection cohomology Hodge module for toric varieties. More precisely, we study the cohomology sheaves of the graded de Rham complex of the intersection cohomology Hodge module and give a precise formula relating it with the stalks of the intersection cohomology as a constructible complex. The main idea is to use the Ishida complex in order to compute the higher direct images of the sheaf of reflexive differentials.
