DMS-0201695John R. KleinThis proposal contains two programs. The first is to study a variety of homotopy theoretic problems associated with space of smooth embeddings of one manifold in another. Among these problems are obstruction theory for embeddings, linking phenomena, compression problems and splitting questions. The second program is a new approach to the study of the equivariant structure sets of topological manifolds equipped with a tame action of a finite group. The new ingredient is to use Poincare embeddings to analyse the difference between the equivariant structures and the isovariant ones.A manifold is a topological space which is locally euclidean. A fundamental problem in topology is to enumerate the embeddings one manifold into another one. The set of all such embeddings forms a topological space. The first part of this proposal is to study various topological aspects of the space of embeddings. The second part concerns the classification of manifolds equipped with a finite group of symmetries.

DMS-0201695John R.克莱因这个建议包含两个方案。首先是研究各种同伦理论问题与空间的光滑嵌入一个流形在另一个。这些问题包括嵌入的阻碍理论、链接现象、压缩问题和分裂问题。第二个程序是研究具有有限群的驯服作用的拓扑流形的等变结构集的一种新方法。新的内容是利用Poincare嵌入来分析等变结构和等变结构之间的区别。流形是局部欧氏的拓扑空间。拓扑学中的一个基本问题是枚举一个流形到另一个流形的嵌入。所有这些嵌入的集合形成一个拓扑空间。这个建议的第一部分是研究嵌入空间的各种拓扑方面。第二部分涉及的分类流形配备了有限群的对称性。
