Embedding Semigroup $C^{*}$ -algebras into Inductive Limits

E. V. Lipacheva

The note is concerned with inductive systems of Toeplitz algebras and their $*$ -homomorphisms over arbitrary partially ordered sets. The Toeplitz algebra is the reduced semigroup $…

Nets of graded $C^{*}$ -algebras over partially ordered sets

S. A. Grigoryan, E. V. Lipacheva, A. S. Sitdikov

The paper deals with $C^{*}$ -algebras generated by a net of Hilbert spaces over a partially ordered set. The family of those algebras constitutes a net of $C^{*}$ -algebras over the sam…

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…
