Conjugate points in the Grassmann manifold of a $C^{*}$ -algebra

Esteban Andruchow, Gabriel Larotonda, Lázaro Recht

Let $G r$ be a component of the Grassmann manifold of a $C^{*}$ -algebra, presented as the unitary orbit of a given orthogonal projection $G r = G r (P)$ . There are several natural connecti…

Symmetries and reflections from composition operators in the disk

Esteban Andruchow, Gustavo Corach, Lázaro Recht

We study the composition operators $C_{a}$ acting on the Hardy space $H^{2}$ of the unit disk, given by $C_{a} f = f \circ φ_{a}$ , where $φ_{a} (z) = \frac{a - z}{1 - a ˉ z},$ for $∣ a ∣ < 1$ . These…
