摘要

本文给出了作用于紧的范畴及其连续映射中的正规函子F。该函子不保留苏斯林数(或遗传细胞数)、遗传密度、遗传π重和遗传沙宁数、遗传口径、遗传前口径、遗传前沙宁数、遗传弱密度、遗传Lindelöf数和密实的遗传程度。给出了正常函子的例子和Aleksandorv的两个箭头的紧致。研究了函子expn, expω, expc和exp在最终紧、遗传不紧、强零维、极度不紧、准紧空间上的作用。

Topological properties of hyperspaces
In the work, it is given the normal functor F acting in the category of compacts and their continuous mappings. This functor does not preserve the Souslin number (or hereditary cellularity), the hereditary density, the hereditary π-weight and the hereditary Shanin number, the hereditary caliber, the hereditary precaliber, the hereditary preshanin number, the hereditary weak density, the hereditary Lindelöf number, and the hereditary extent of a compact. The example of the normal functor and the compact of Aleksandorv’s two arrows are given. We study the action of functors expn, expω, expc and exp on finally compact, hereditarily disconnected, strongly zero-dimensional, extremely disconnected, paracompact spaces.
