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 ...

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 ...

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

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 ...

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.

Locally compact topologies for groups [PDF]

open access: yesTransactions of the American Mathematical Society, 1967
The investigations leading to this paper were suggested by the papers of Hewitt [3] and Ross [5]. In [3] Hewitt was interested in proving that if an abelian group is locally compact in two topologies, one strictly stronger than the other, there is a character continuous in one topology and discontinuous in the other (actually a special case of a ...

Uniformly continuous functionals on the Fourier algebra of any locally compact group

open access: yes, 1979
Let G be any locally compact group. Let VN(G) be the von Neumann algebra generated by the left regular representation of G. We study in this paper the closed subspace UBC(G) of VN(G) consisting of the uniformly continuous functionals as defined by E ...

Countable sections for locally compact group actions

open access: yesErgodic Theory and Dynamical Systems, 1992
It has been shown by J. Feldman, P. Hahn and C. C. Moore that every non-singular action of a second countable locally compact group has a countable (in fact so-called lacunary) complete measurable section.
