The Fréchet derivative is in the first Baire class

Eva Kopecká, Luděk Zaj\'ıček

Let $X$ be a normed linear space, $Y$ a Banach space, $G \subset X$ an open set and $f : G \to Y$ a mapping. We show that the Fréchet derivative $f^{'}$ of $f$ is of the first Baire clas…

When products of projections diverge

Eva Kopecka

Slow convergence of cyclic projections implies divergence of random projections and vice versa. Let $L_{1}, L_{2}, \dots, L_{K}$ be a family of $K$ closed subspaces of a Hilbert space. It i…

A note on alternating projections in Hilbert space

Eva Kopecka, Simeon Reich

We provide a direct proof of a result regarding the asymptotic behavior of alternating nearest point projections onto two closed and convex sets in a Hilbert space. Our arguments a…
