This paper is aimed to investigate the strong -closure of the vector fields on the open unit ball that are smooth up to finitely many integer point singularities. First, such strong closure is characterized for arbitrary . Secondly, it is shown what happens if the integrability order p is large enough (namely, if ). Eventually, a decomposition theorem for elements in is given, conveying information about the possibility of connecting the singular set of such vector fields by a mass-minimizing, integer 1-current on B with finite mass.

本文旨在调查强 -关闭 单位球上矢量场的分布 平滑到有限的整数整数奇点。首先,这种强力的封闭具有任意性的特点。其次,显示出如果可积阶数p足够大(即,如果)。最终,分解定理为给出了传递有关通过矢量以有限质量在B上进行质量最小化的整数1-电流连接这种矢量场的奇异集的可能性的信息。
