一、主体不同 1、compact set：又叫紧集，是指拓扑空间内的一类特殊点集，它们的任何开覆盖都有有限子覆盖。2、closed set：又叫闭集，在拓扑空间中，闭集是指其补集为开集的集合。二、特点不同 1、compact set：任何开覆盖都有有限子覆盖。从某种意义上，紧集类似于闭集。2、closed set：任意多个闭...
一个简单的例子：球面是闭的，也是紧的；但是如果在球面上挖去一个开圆盘，此时得到的一个紧的，但非...
但不是compact的，因为无界；但是一条线段就是compact的因为既是闭集又有界

In this paper we first observe that the complement of a countable closed subset of an n-dimensional manifold M has large (n - 1)-homology group. In the last section we use this information to prove that, under some topological conditions on the given manifold, certain families of fibers, ...
We also discuss the existence of compact\nnon-approximable operators $X o Y$, where $X \\subset \\ell^p$ and $Y \\subset\n\\ell^q$ are closed subspaces for $p eq q$.doi:10.48550/arXiv.2105.08403Tylli, Hans-OlavWirzenius, Henrik...
only a subset of the 37 possible features is given at each time point. We perform the same test–train split and preprocessing as in ref.7, and report the area under the curve (AUC) on the test set as a metric in Extended Data Fig.6. We observe that CfCs perform competitively to ot...
