Homogeneous linearly ordered spaces

Anton Lipin, Evgenii Reznichenko

Every compact subset of a homogeneous generalized ordered (GO) space has character at most $ω_{1}$ and cardinality at most $2^{ω_{1}}$ ; if such a subset has uncountable character, then…

Resolvability in products of spaces of small cardinality

Anton Lipin

We prove that: I. The product of any two regular isodyne spaces of cardinality $ω_{1}$ is $ω$ -resolvable; II. The product of any $n + 2$ Hausdorff isodyne spaces of cardinality $ω_{n}$ …

$R^{ω_{1}}$ -Factorizable Spaces and Groups

Anton Lipin, Evgenii Reznichenko, Ol'ga Sipacheva

A topological space $X$ is $R^{ω_{1}}$ -factorizable if any continuous function $f : X \to R^{ω_{1}}$ factors through a continuous function from $X$ to a second-count…

Resolvability in products and squares

Anton Lipin

Suppose $X$ and $Y$ are topological spaces, $∣ X ∣ = Δ (X)$ and $∣ Y ∣ = Δ (Y)$ . We investigate resolvability of the product $X \times Y$ . We prove that: I. If $∣ X ∣ = ∣ Y ∣ = ω$ and $X, Y$ …

Relatively functionally countable subsets of products

Anton Lipin

A subset $A$ of a topological space $X$ is called relatively functionally countable (RFC) in $X$ , if for each continuous function $f : X \to R$ the set $f [A]$ is countable…

Tightness type properties of spaces of quasicontinuous functions

Anton E. Lipin, Alexander V. Osipov

Using approximation by continuous functions we prove the following statements to types of tightness in a space $Q_{p} (X, R)$ of all quasicontinuous real-valued functions wit…

On resolvability and tightness in uncountable spaces

Anton Lipin

We investigate connections between resolvability and different forms of tightness. This study is adjacent to [1,2]. We construct a non-regular refinement $τ^{*}$ of the natural topol…

On resolvability, connectedness and pseudocompactness

Anton Lipin

We prove that: I. If $L$ is a $T_{1}$ space, $∣ L ∣ > 1$ and $d (L) \leq κ \geq ω$ , then there is a submaximal dense subspace $X$ of $L^{2^{κ}}$ such that $∣ X ∣ = Δ (X) = κ$ ; II. If $\frak{c}\leqκ…

Resolvability and complete accumulation points

A. E. Lipin

We prove that: I. For every regular Lindelöf space $X$ if $∣ X ∣ = Δ (X)$ and $cf ∣ X ∣ \neq = ω$ , then $X$ is maximally resolvable; II. For every regular countably compact space $X$ i…
