Peripheral Covering Properties Imply Covering Properties

Canadian Journal of Mathematics, 1968
Recently several papers (11; 12; 13; 14) have been published in which it is shown that a Moore space (normal, in one case) is metrizable if it has the peripheral version (in the sense defined below) of a certain covering property that was known to imply metrizability of Moore spaces. Each of these metrization theorems can be proved more easily by using

Some Covering Properties Using Fuzzy Maximal Covers

Tuijin Jishu/Journal of Propulsion Technology, 2023
The aim of this article is to define fuzzy maximal open cover and discuss its few properties. we also defined and study fuzzy m-compact space and discussed its properties. Also we obtain few more results on fuzzy minimal c-regular and fuzzy minimal c-normal spaces. We have proved that a fuzzy Haussdorff m-compact space is fuzzy minimal c- normal.

Covering Properties of Convex Sets

Bulletin of the London Mathematical Society, 1986
Partant d'un recouvrement ouvert de certains convexes d'un espace vectoriel topologique séparé, l'A. obtient un recouvrement fermé contenu dans le premier. Le caractère fermé du recouvrement lui permet alors d'utiliser un résultat classique afin d'obtenir une démonstration élégante d'un résultat récent de Ky Fan.

Permutation Groups and Covering Properties

Journal of the London Mathematical Society, 2001
The author considers the relationships between a number of cardinal invariants of the continuum. A subgroup \(G\) of the full symmetric group \(\text{Sym}(\omega)\) is `cofinitary' if each non-identity element has only finitely many fixed points [see \textit{P. J. Cameron}, Bull. Lond. Math. Soc. 28, No.
