West semigroups as compactifications of locally compact abelian groups

open access: yes, 2016
In this paper, we will identify certain subsemigroups of the unit ball of as semitopological compactifications of locally compact abelian groups, using an idea of West (Proc R Ir Acad Sect A 67:27-37, 1968).

Locally compact groups which have the weakly compact homomorphism property

open access: yes, 1995
A locally compact group G is WCHP if every weakly compact homomorphism from L 1 ( G ) {L^1}(G) into a Banach algebra has finite-dimensional range, and is

Principal Component Analysis for a Stationary Random Function Defined on a Locally Compact Abelian Group

open access: yes, 1994
When Z is a random L2H-valued measure, where H is a Hilbert space, we prove that there exists an L2Cq-valued measure, which may depend on constraints and which best sums up the random measure Z according to a stationary criterion.

On Almost Convergence on Locally Compact Abelian Groups

open access: yesJournal of Fourier Analysis and Applications
We study a summability method called almost convergence for bounded measurable functions defined on a locally compact abelian group. We define almost convergence using topologically invariant means and exhibit two different kinds of necessary and sufficient conditions, one is analytic and the other is functional analytic, for a given function to be ...

Small doubling implies small tripling for balls of large radius

open access: yesDiscrete Analysis
Small doubling implies small tripling for balls of large radius, Discrete Analysis 2025:9, 9 pp. In additive combinatorics, the well-known Plünnecke--Ruzsa inequalities state that if $A$ is a finite nonempty subset of an abelian group satisfying $|2A ...
