具有非均匀各向异性介质的不规则外区域上加权索伯列夫空间的Hodge-Helmholtz分解

Hodge-Helmholtz Decompositions of Weighted Sobolev Spaces in Irregular Exterior Domains with Inhomogeneous and Anisotropic Media

Dirk Pauly

摘要:

我们详细研究了充满非均匀和各向异性介质的非光滑外部区域中的Hodge-Helmholtz分解。我们展示了属于加权索伯列夫空间的交替微分形式分解成无旋和螺线管形式。这些分解是重要的工具,例如,在电磁理论的外部域。在附录中,我们将我们的结果转化为向量分析的经典框架。

英文摘要:

We study in detail Hodge-Helmholtz decompositions in non-smooth exterior domains filled with inhomogeneous and anisotropic media. We show decompositions of alternating differential forms belonging to weighted Sobolev spaces into irrotational and solenoidal forms. These decompositions are essential tools, for example, in electro-magnetic theory for exterior domains. In the appendix we translate our results to the classical framework of vector analysis.
