Extensions of C*-algebras and translation invariant asymptotic homomorphisms

V. Manuilov, K. Thomsen

Let $A$ , $B$ be C*-algebras; $A$ separable, $B$ $σ$ -unital and stable. We introduce a notion of translation invariance for asymptotic homomorphisms from $SA=C_0(\mathbb R)\otimes A…

Semi-invertible extensions and asymptotic homomorphisms

V. Manuilov, K. Thomsen

We consider the semigroup $E x t (A, B)$ of extensions of a separable C*-algebra $A$ by a stable C*-algebra $B$ modulo unitary equivalence and modulo asymptotically split extensions. T…
