A note on linear approximately orthogonality preserving mappings

Ye Zhang, Yanni Chen, Don Hadwin +1

In this paper, linear $ε$ -orthogonality preserving mappings are studied. We define $ε^(T)$ as the smallest $ε$ for which $T$ is $\var…

Lebesgue and Hardy Spaces for Symmetric Norms II: A Vector-Valued Beurling Theorem

Yanni Chen, Don Hadwin, Ye Zhang

Suppose $α$ is a rotationally symmetric norm on $L^{\infty} (T)$ and $β$ is a "nice" norm on $L^{\infty} (Ω, μ)$ where $μ$ is a $σ$ -finite measure on…

Lifting Normal Elements in Nonseparable Calkin Algebras

Ye Zhang, Don Hadwin, Yanni Chen

We use the remarkable distance estimate of Ilya Kachkovskiy and Yuri Safarov, to show that if $H$ is a nonseparable Hilbert space and $K$ is any closed ideal in $B (H)$ that is not…
