关于满足序列选择性质的集合的几何

On the Geometry of sets satisfying the Sequence Selection Property

Satoshi Koike, Laurentiu Paunescu

摘要:

本文研究了在条件(SSP)假设下集合的基本方向性质。我们证明了几个横截性定理在奇异的情况下和(SSP)-结构保持定理。作为一个例子,我们的横截性结果被用来证明几个事实,复解析簇。(SSP)-性质最适合于理解Lipschitz范畴中的横截性。这个属性是共享的一大类集,特别是由subanalytic集或可定义集的O-最小结构。

英文摘要:

In this paper we study fundamental directional properties of sets under the assumption of condition (SSP) (introduced in a previous paper). We show several transversality theorems in the singular case and an (SSP)-structure preserving theorem. As an illustration, our transversality results are used to prove several facts concerning complex analytic varieties. The (SSP)-property is most suitable for understanding transversality in the Lipschitz category. This property is shared by a large class of sets, in particular by subanalytic sets or by definable sets in an o-minimal structure.
