THE BOHR COMPACTIFICATION OF AN ARITHMETIC GROUP
Autor: Bekka, Bachir
Given a group $\Gamma,$ its Bohr compactification $\operatorname{Bohr}(\Gamma)$ and its profinite completion $\operatorname{Prof}(\Gamma)$ are compact groups naturally associated to $\Gamma$; moreover, $\operatorname{Prof}(\Gamma)$ can be identified

Symétrie et gravitation
Autor: Henneaux, Marc, Römer, Thomas
En suivant deux fils rouges, l’histoire des grandes révolutions de la physique au xxe siècle et l’abstraction progressive du concept de symétrie, de son usage ordinaire en géométrie à son application aux lois de la physique, cette leçon in

The string C-group representations of the Suzuki, Rudvalis and O'Nan sporadic groups
Autor: Jessica Mulpas, Dimitri Leemans
Publikováno v: The art of discrete and applied mathematics
We present new algorithms to classify all string C-group representations of a given group G. We use these algorithms to classify all string C-group representations of the Suzuki, Rudvalis and O’Nan sporadic groups. The new rank three algorithms als

Nuclear Group Algebras for Finitely Generated Groups

Publikováno v: Bulletin of the Belgian Mathematical Society Simon Stevin
Bull. Belg. Math. Soc. Simon Stevin 27, no. 4 (2020), 567-594
We study completions of the group algebra of a finitely generated group and relate nuclearity of such a completion to growth properties of the group. This extends previous work of Jolissaint on nuclearity of rapidly decreasing functions on a finitely

Théorie des modèles métriques, groupes polonais et diversités
Autor: Hallbäck, Andreas
Publikováno v: Logic [math.LO]. Université de Paris, 2020. English. ⟨NNT : 2020UNIP7078⟩
We study metric model theory and Polish groups as automorphism groups of separable metric structures. We expand upon the infinitary continuous logic treated in [12, 11, 23, 27] and give a new proof of the Omitting Types Theorem of infinitary continuo

STUDY ON NON-LINEAR STRUCTURES
Autor: Le Corre, Stéphane
The objective of this article is to define a new geometrical space which extends the notion of vector to geometrical objects which we will name sector (portion of surface in the form of parallelogram). We will extract from it 3 propositions of algebr

On chiral polytopes having a group PSL(3,q) as automorphism group
Autor: Leemans, Dimitri, Vandenschrick, Adrien
Publikováno v: Journal of the London Mathematical Society
For each prime power $q\geq 5$, we construct a rank four chiral polytope that has a group $PSL(3,q)$ as automorphism group and Schl\"afli type $\{q-1,\frac{2(q-1)}{(3,q-1)},q-1\}$. We also construct rank five polytopes for some values of $q$ and we s
