Noncommutative Cantor-Bendixson derivatives and scattered $C^{*}$ -algebras

Saeed Ghasemi, Piotr Koszmider

We analyze the sequence obtained by consecutive applications of the Cantor-Bendixson derivative for a noncommutative scattered $C^{*}$ -algebra $A$ , using the ideal $\mathcal…

An extension of compact operators by compact operators with no nontrivial multipliers

Saeed Ghasemi, Piotr Koszmider

We construct an essential extension of $K (ℓ_{2} (c))$ by $K (ℓ_{2})$ , where $c$ denotes the cardinality of continuum, i.e., a $C^{*}$ -alge…
