Shannon’s theorem for locally compact groups [PDF]

open access: yesThe Annals of Probability, 2022
We consider random walks on locally compact groups, extending the geometric criteria for the identification of their Poisson boundary previously known for discrete groups. First, we prove a version of the Shannon-McMillan-Breiman theorem, which we then use to generalize Kaimanovich's ray approximation and strip approximation criteria.

A dichotomy property for locally compact groups [PDF]

open access: yes, 2018
We extend to metrizable locally compact groups Rosenthal's theorem describing those Banach spaces containing no copy of $l_1$. For that purpose, we transfer to general locally compact groups the notion of interpolation ($I_0$) set, which was defined by ...

Derivative for Functions f:GH, Where G Is a Metric Divisible Group

open access: yesMathematics, 2022
In this paper, a derivative for functions f:G→H, where G is any metric divisible group and H is a metric Abelian group with a group metric, is defined. Basic differentiation theorems are stated and demonstrated. In particular, we obtain the Chain Role.

Conjugacy class conditions in locally compact second countable groups [PDF]

open access: yes, 2015
Many non-locally compact second countable groups admit a comeagre conjugacy class. For example, this is the case for the automorphism group of the rational order and the automorphism group of the random graph [Truss]. A. Kechris and C.

On Character Space of the Algebra of BSE-functions [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2018
Suppose that $A$ is a semi-simple and commutative Banach algebra. In this paper we try to characterize the character space of the Banach algebra $C_{rm{BSE}}(Delta(A))$ consisting of all  BSE-functions on $Delta(A)$ where $Delta(A)$ denotes the character

Asymptotic invariants of lattices in locally compact groups

open access: yesComptes Rendus. Mathématique, 2023
The aim of this work is to understand some of the asymptotic properties of sequences of lattices in a fixed locally compact group. In particular we will study the asymptotic growth of the Betti numbers of the lattices renormalized by the covolume and the

Locally compact convergence groups and n-transitive actions [PDF]

open access: yes, 2012
All sigma-compact, locally compact groups acting sharply n-transitively and continuously on compact spaces M have been classified, except for n=2,3 when M is infinite and disconnected. We show that no such actions exist for n=2 and that these actions for

Compact Subgroups of Lie Groups and Locally Compact Groups [PDF]

open access: yesProceedings of the American Mathematical Society, 1994
We show that the set of compact subgroups in a connected Lie group is inductive. In fact, a locally compact group G G has the inductivity property for compact subgroups if and only if the factor group G / G 0 G/{G_0} modulo the ...

Coherent Frames [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2018
Frames which can be generated by the action of some operators (e.g. translation, dilation, modulation, ...) on a single element $f$ in a Hilbert space, called coherent frames.

The weights of closed subgroups of a locally compact group [PDF]

open access: yes, 2012
Let $G$ be an infinite locally compact group and $\aleph$ a cardinal satisfying $\aleph_0\le\aleph\le w(G)$ for the weight $w(G)$ of $G$. It is shown that there is a closed subgroup $N$ of $G$ with $w(N)=\aleph$.
