Lifting of nilpotent contractions

Tatiana Shulman

It is proved that that every nilpotent contraction in a quotient C*-algebra can be lifted to a nilpotent contraction. As a consequence we get that the universal C*-algebra generate…

On universal C^*-algebras generated by n projections with scalar sum

Tatiana Shulman

We study the universal C^*-algebras generated by n projections $p_{1}, > ..., p_{n}$ subject to the relation $p_{1} + ... p_{n} = λ 1$ , $λ \in R$ . The questions of when these C^*-algebr…

The C*-algebras qA\otimes K and S^2A\otimes K are asymptotically equivalent

Tatiana Shulman

Let $A$ be a separable $C^{*}$ -algebra. We prove that its stabilized second suspension $S^{2} A \otimes K$ and the $C^{*}$ -algebra $q A \otimes K$ constructed by Cuntz in t…
