We present a wide class of reflexive, precompact, non-compact, Abelian topological groups G determined by three requirements. They must have the Baire property, satisfy the open refinement condition, and contain no infinite compact subsets. This combination of properties guarantees that all compact subsets of the dual group G∧ are finite. We also show that many (non-reflexive) precompact Abelian groups are quotients of reflexive precompact Abelian groups. This includes all precompact almost… Expand
Duality properties of bounded torsion topological abelian groups
Abstract Let G be a precompact, bounded torsion abelian group and G p ∧ its dual group endowed with the topology of pointwise convergence. We prove that if G is Baire (resp., pseudocompact), then allExpand
A survey on reflexivity of abelian topological groups
The Pontryagin duality theorem for locally compact abelian groups (briefly, LCA groups) has been the starting point for many different routes of research in Mathematics. From its appearance there wasExpand
Some cases of preservation of the Pontryagin dual by taking dense subgroups
Abstract We study the compact-open topology on the character group of dense subgroups of topological abelian groups. Permanence properties concerning open subgroups, quotients and products areExpand
Metrization criteria for compact groups in terms of their dense subgroups
According to Comfort, Raczkowski and Trigos-Arrieta, a dense subgroup D of a compact abelian group G determines G if the restriction homomorphism G^ --> D^ of the dual groups is a topologicalExpand

On convergent sequences in dual groups
We provide some characterizations of precompact abelian groups G whose dual group $$G_p^\wedge $$ G p ∧ endowed with the pointwise convergence topology on elements of G contains a nontrivialExpand
On reflexivity of the group of the null sequences valued in an Abelian topological group
We prove that the group F0(X) of all X-valued null sequences endowed with the uniform topology is reflexive for every locally compact Abelian group X. This gives a wide class of complete reflexiveExpand
Reflecting some properties of topological groups
We show that for a number of cardinal functions ϕ, an ω-narrow topological group G admits a continuous homomorphism onto a topological group H satisfying ϕ(H)=w(H)=τ, for every infinite regularExpand
Baire property in product spaces
We show that if a product space $\mathit\Pi$ has countable cellularity, then a dense subspace $X$ of $\mathit\Pi$ is Baire provided that all projections of $X$ to countable subproducts ofExpand
Paratopological and Semitopological Groups Versus Topological Groups
We present a survey on paratopological and semitopological groups relating these classes with the class of topological groups. A special attention is given to compactness-type properties inExpand


Precompact noncompact reflexive Abelian groups
Abstract. We study Pontryagin reflexivity in the class of precompact topological Abelian groups. We find reflexive groups among precompact not pseudocompact and among pseudocompact not compactExpand
An approach to duality on abelian precompact groups
Abstract We prove that every dense subgroup of a topological abelian group has the same ‘convergence dual’ as the whole group. By the ‘convergence dual’ we mean the character group endowed with theExpand
Pontryagin duality for metrizable groups
Abstract. This paper deals with the validity of the Pontryagin duality theorem in the class of metrizable topological groups. We prove that completeness is a necessary condition for the PontryaginExpand

Open subgroups and Pontryagin duality
For an abelian topological group G, let G∧ denote the character group of G. The group G is called reflexive if the evaluation map is a topological isomorphism of G onto G∧∧, and G is called stronglyExpand
