چکیده

Abstract In the absence of axiom choice, set-theoretic status many natural statements about metrizable compact spaces is investigated. Some are provable in $$\mathbf {ZF}$$ ZF , some shown to be independent . For independence results, distinct models and permutation {ZFA}$$ ZFA with transfer theorems Pincus applied. New symmetric constructed each which power set $$\mathbb {R}$$ R well-orderable, Continuum Hypothesis satisfied but a denumerable family non-empty finite sets can fail have choice function, space need not embeddable into Tychonoff cube $$[0, 1]^{\mathbb {R}}$$ [ 0 , 1 ]

Countable Compact Hausdorff Spaces Need Not Be Metrizable in Zf

We show that the existence of a countable, first countable, zerodimensional, compact Hausdorff space which is not second countable, hence not metrizable, is consistent with ZF. 1. Notation and terminology Definition 1.1. Let (X,T ) be a topological space and B a base for T . (i) X is said to be compact if every open cover U of X has a finite subcover V . X is said to be compact with respect to ...

Compact Monotonically Metacompact Spaces Are Metrizable

Monotonically metacompact spaces were recently introduced as an extension of the concept of monotonically compact spaces. In this note we answer a question of Popvassilev, and Bennett, Hart, and Lutzer, by showing that every compact, Hausdorff, monotonically (countably) metacompact space is metrizable. We also show that certain countable spaces fail to be monotonically (countably) metacompact.

Compact Metrizable Groups Are Isometry Groups of Compact Metric Spaces

This note is devoted to proving the following result: given a compact metrizable group G, there is a compact metric space K such that G is isomorphic (as a topological group) to the isometry group of K.

On D-dimension of metrizable spaces*

For every cardinal τ and every ordinal α, we construct a metrizable space Mα(τ) and a strongly countable-dimensional compact space Zα(τ) of weight τ such that D(Mα(τ)) ≤ α, D(Zα(τ)) ≤ α and each metrizable space X of weight τ such that D(X) ≤ α is homeomorphic to a subspace of Mα(τ) and to a subspace of Zα+1(τ).
