Unitary operators with decomposable corners

Esteban Andruchow

We study pairs $(U, L_{0})$ , where $U$ is a unitary operator in $H$ and $L_{0} \subset H$ is a closed subspace, such that $P_{L_{0}} U ∣_{L_{0}} : L_{0} \to L_{0}$ has a singular value decomposit…

A non commutative Kähler structure on the Poincaré disk of a C*-algebra

Esteban Andruchow, Gustavo Corach, Lázaro Recht

We study the Poincaré disk $\d=\{z\in\a: \|z\|<1\}$ of a C $^{*}$ -algebra $\a$ as a homogeneous space under the action of an appropriate Banach-Lie group $(˘ θ)$ of $2 \times 2$ matric…

The C*-algebra of compact perturbations of diagonal operators

Esteban Andruchow, Eduardo Chiumiento, Alejandro Varela

We study the elementary C*-algebra whose elements are the sum of a diagonal plus a compact operator. We describe the structure of the unitary group, the sets of ideals, automorhism…
