Semigroup Operator Algebras and Quantum Semigroups

Marat Aukhadiev, Suren Grigoryan, Ekaterina Lipacheva

A detailed study of the semigroup $C^{*}$ -algebra is presented. This $C^{*}$ -algebra appears as a "deformation" of the continuous functions algebra on a compact abelian group. Co…

On $π$ -extensions of the semigroup $Z_{+}$

T. A. Grigoryan, E. V. Lipacheva, V. H. Tepoyan

We study inverse $π$ -extensions of the semigroup $Z_{+}$ . It is shown that $π$ -extension of the semigroup $Z_{+}$ is inverse, iff its $π$ -extension coincides with $π(…

On The Extension of the Toeplitz Algebra by Isometries

T. A. Grigoryan, E. V. Lipacheva, V. H. Tepoyan

We introduce the notion of π-extension of the semigroup \mathbb{Z}_+ and study the extensions of the Toeplitz algebras by isometric operators. We show that when the action of the T…
