Poncaré half-space of a C*-algebra

Esteban Andruchow, Gustavo Corach, Lázaro Recht

Let $A$ be a C$*^$-algebra. Given a representation $A \subset B (L)$ in a Hilbert space $L$ , the set $G^{+} \subset A$ of positive invertible elements can be thought as the set of inner…

Schmidt decomposable products of projections

Esteban Andruchow, Gustavo Corach

We characterize operators $T = P Q$ ( $P, Q$ orthogonal projections in a Hilbert space $H$ ) which have a singular value decomposition. A spatial characterizations is given: this conditi…

Essentially orthogonal subspaces

Esteban Andruchow, Gustavo Corach

We study the set $C$ consisting of pairs of orthogonal projections $P, Q$ acting in a Hilbert space $H$ such that $P Q$ is a compact operator. These pairs have a rich g…

Uncertainty principle and geometry of the infinite Grassmann manifold

Esteban Andruchow, Gustavo Corach

We study the pairs of projections $P_{I} f = χ_{I} f, Q_{J} f = (χ_{J} f^) ˇ, f \in L^{2} (R^{n}),$ where $I, J \subset R^{n}$ are sets of finite Le…
