On a topology and limits for inductive systems of $C^{*}$ -algebras over partially ordered sets

Renat Gumerov, Ekaterina Lipacheva, Tamara Grigoryan

Motivated by algebraic quantum field theory and our previous work we study properties of inductive systems of \ $C^{*}$ -algebras over arbitrary partially ordered sets. A partially or…

$C^{*}$ -algebras generated by the paths semigroup

Suren Grigoryan, Tamara Grigoryan, Ekaterina Lipacheva +1

In this paper we study the structure of the $C^{*}$ -algebra, generated by the representation of the paths semigroup on a partially ordered set (poset) and get the net of isomorphic $…

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…
