局部对偶与混合Hodge模

Local duality and mixed Hodge modules

Christian Schnell

摘要:

在光滑代数簇上的极化Hodge模的基础上,建立了过滤完整D-模的分次导数、层理论导数和特征簇之间的关系.证明是基于Saito的结果,即相关的分次模是Cohen-Macaulay,和余切丛上的局部对偶。

英文摘要:

We establish a relationship between the graded quotients of a filtered holonomic D-module, their sheaf-theoretic duals, and the characteristic variety, in case the filtered D-module underlies a polarized Hodge module on a smooth algebraic variety. The proof is based on Saito's result that the associated graded module is Cohen-Macaulay, and on local duality on the cotangent bundle.
