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…

Geometry of unitary orbits of pinching operators

Eduardo Chiumiento, María E. Di Iorio y Lucero

Let I be a symmetrically-normed ideal of the space of bounded operators acting on a Hilbert space H. Let $p_{i}_{1}^{w}$ $(1 \leq w \leq \infty)$ be a family of mutually orthogonal pro…
