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

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.

The diamond covering property axiom

Mathematical Logic Quarterly, 2016
The Covering Property Axiom, which attempts to capture some of the combinatorics of the Sacks model, the model obtained from by countable support iteration of length of the Sacks forcing, seems to miss a Suslin tree. We add a diamond polish to the axiom to remedy this.
