Pseudocompactness and Closed Subsets of Products [PDF]

open access: yesProceedings of the American Mathematical Society, 1979
This paper contains several new characterizations of arbitrary pseudocompact spaces, i.e. spaces characterized by the property that all continuous real-valued functions on the space are bounded. These characterizations parallel known characterizations of Hausdorff spaces including the useful and well-known result that a space

Extremal pseudocompact topological groups

open access: yes, 2004
Topological groups here are assumed to satisfy the Hausdorff separation property. A topological group G is totally bounded if it embeds as a (dense) subgroup of a compact group G¯; here G¯, the Weil completion of G, is unique in the obvious sense.

Pseudocompact group topologies with no infinite compact subsets [PDF]

open access: yes, 2009
We show that every Abelian group satisfying a mild cardinal inequality admits a pseudocompact group topology from which all countable subgroups inherit the maximal totally bounded topology (we say that such a topology satisfies property ).

The group of characters of a pseudocompact locally compact semitopological semigroup

open access: yesApplied General Topology
We prove that each semitopological semigroup has a reflection in the class of abelian cancellative semitopological semigroups. Then we use this reflection to prove that the group of characters of a locally compact pseudocompact topological semigroup with

Iterated starcompact topological spaces

open access: yesApplied General Topology, 2004
Let P be a topological property. A space X is said to be k-P-starcompact if for every open cover U of X, there is a subspace A C X with P such that stk(A,U) = X.

F-points in countably compact spaces

open access: yesApplied General Topology, 2001
Answering a question of A.V. Arhangel'skii, we show that any extremally disconnected subspace of a compact space with countable tightness is discrete.

Three examples of pseudocompact quasitopological groups

open access: yes, 2006
A quasitopological group is an abstract group with topology in which the inversion and all translations are continuous. We show that a pseudocompact quasitopological group of countable cellularity need not be a Moscow space. Then we present an example of

An operation on topological spaces

open access: yesApplied General Topology, 2000
A (binary) product operation on a topological space X is considered. The only restrictions are that some element e of X is a left and a right identity with respect to this multiplication, and that certain natural continuity requirements are satisfied ...

On pseudo-k-spaces

open access: yesApplied General Topology, 2008
In this note a new class of topological spaces generalizing k-spaces, the pseudo-k-spaces, is introduced and investigated. Particular attention is given to the study of products of such spaces, in analogy to what is already known about k-spaces and quasi-
