A non-stable C*-algebra with an elementary essential composition series

Saeed Ghasemi, Piotr Koszmider

A C*-algebra $A$ is said to be stable if it is isomorphic to $A \otimes K (ℓ_{2})$ . Hjelmborg and Rørdam have shown that countable inductive limits of separable stable C*-algebras…

C*-Algebras With and Without $≪$ -Increasing Approximate Units

Tristan Bice, Piotr Koszmider

For elements $a, b$ of a C*-algebra we denote $a = ab$ by $a ≪ b$ . We show that all $ω_{1}$ -unital C*-algebras have $≪$ -increasing approximate units, extending a classical result fo…
