Computing the Scale of an Endomorphism of a totally Disconnected Locally Compact Group

open access: yesAxioms, 2017
The scale of an endomorphism of a totally disconnected, locally compact group G is defined and an example is presented which shows that the scale function is not always continuous with respect to the Braconnier topology on the automorphism group of G ...

Splitting of extensions in the category of locally compact abelian groups [PDF]

open access: yesInternational Journal of Group Theory, 2014
Let $pounds$ be the category of all locally compact abelian (LCA) groups. In this paper, the groups $G$ in $pounds$ are determined such that every extension $0to Xto Yto Gto 0$ with divisible, $sigma-$compact $X$ in $pounds$ splits. We also determine the

Slice Theorem For Differential Spaces And Reduction By Stages

open access: yesDemonstratio Mathematica, 2014
We show that the space P/G of orbits of a proper action of a Lie group G on a locally compact differential space P is a locally compact differential space with quotient topology.

On generalization of homotopy axiom

open access: yesPracì Mìžnarodnogo Geometričnogo Centru, 2023
In [S. Kermit, Proc. Amer. Math. Soc., 1972, 31(1):271-275] it was proven that if G is compact topological group or field then in the homotopy axiom for Alexander-Spanier-Kolmogoroff cohomology the parameter segment [0;1] can be replaced by any compact ...

On locally compact semitopological O-bisimple inverse ω-semigroups

open access: yesTopological Algebra and its Applications, 2018
We describe the structure of Hausdorff locally compact semitopological O-bisimple inverse ω- semigroups with compact maximal subgroups. In particular, we show that a Hausdorff locally compact semitopological O-bisimple inverse ω-semigroup with a compact ...

Krein’s Theorem in the Context of Topological Abelian Groups

open access: yesAxioms, 2022
A topological abelian group G is said to have the quasi-convex compactness property (briefly, qcp) if the quasi-convex hull of every compact subset of G is again compact.

Spaceability in Banach Spaces Related to Locally Compact Groups

open access: yesپژوهش‌های ریاضی, 2021
In this paper, for a locally compact group  and a fixed number , we give some sufficient conditions for the set  to be spaceable in . Also, by some special Segal algebras which recently have been introduced, we find spaceable subsets of the Fourier ...

Generalized Analogs of the Heisenberg Uncertainty Inequality [PDF]

open access: yes, 2015
We investigate locally compact topological groups for which a generalized analogue of Heisenberg uncertainty inequality hold. In particular, it is shown that this inequality holds for $\mathbb{R}^n \times K$ (where $K$ is a separable unimodular locally ...

Commutative Topological Semigroups Embedded into Topological Abelian Groups

open access: yesAxioms, 2020
In this paper, we give conditions under which a commutative topological semigroup can be embedded algebraically and topologically into a compact topological Abelian group.

On topological groups with remainder of character k

open access: yesApplied General Topology, 2016
In [A.V. Arhangel'skii and J. van Mill, On topological groups with a first-countable remainder, Top. Proc. 42 (2013), 157-163] it is proved that the character of a non-locally compact topological group with a first countable remainder doesn't exceed ...
