[引用][C] Discrete subsets of topological groups

IV Protasov - Mathematical Notes, 1994 - Springer
A subset A of a topological group G is said to be totally bounded if for any neighborhood U of
the identity there exists a finite subset K c G such that A~(KU N UK). If the subset G of a …

[PDF][PDF] A certain type of locally compact totally disconnected topological groups

TS Wu - Proceedings of the American Mathematical Society, 1969 - community.ams.org
Let G be a locally compact totally disconnected topological group. If G contains a closed
subgroup A which is isomorphic with a discrete finitely generated free abelian group, such …

Discrete sets and the maximal totally bounded group topology

KP Hart, J van Mill - Journal of Pure and Applied Algebra, 1991 - Elsevier
If G is an Abelian group, then G# is G with its maximal totally bounded group topology. We
prove that every A⊆ G# contains a closed (in G#) and discrete subset B such that| B|=| A …

On endomorphisms of Abelian topological groups

E Katz, SA Morris - Proceedings of the American Mathematical Society, 1982 - ams.org
A family $\Phi $ of continuous endomorphisms of a topological group $ G $ is said to be
small if for every subgroup $ H $ of $ G $ of cardinality ${\text {card}}(H)<{\text {card}}(G) …

Long chains of Hausdorff topological group topologies

WW Comfort, D Remus - Journal of Pure and Applied Algebra, 1991 - Elsevier
For certain classes A of topological group topologies on a group G, we determine those
cardinals β which arise as the length of a chain in A. We show, for example, that if G is …

[PDF][PDF] Uniform continuity and compactness in topological groups

JM Kister - Proceedings of the American Mathematical Society, 1962 - community.ams.org
A topological group G will be said to have property U if every continuous real-valued
function/on G is uniformly continuous (ie for every e> 0 there is a neighborhood N of the …

Varieties of topological groups

SA Morris - Bulletin of the Australian Mathematical Society, 1970 - cambridge.org
We define a variety V, of topological groups to be a family of topological groups closed
under cartesian products, quotient groups and subgroups. The class of groups, which with …

Nondiscrete topological groups with many discrete subgroups

SA Morris, VN Obraztsov - Topology and its Applications, 1998 - Elsevier
It is shown that for each positive integer n, there exists a nondiscrete Hausdorff topological
group of cardinality ℵ n with no proper subgroup of the same cardinality and with each …

Free products of topological groups

SA Morris - Bulletin of the Australian Mathematical Society, 1971 - cambridge.org
In this note the notion of a free topological product Gα of a set {Gα} of topological groups is
introduced. It is shown that it always exists, is unique and is algebraically isomorphic to the …
