A General Beurling-Helson-Lowdenslager Theorem on the Disk

Yanni Chen

The classical Beurling-Helson-Lowdenslager theorem characterizes the shift-invariant subspaces of the Hardy space $H^{2}$ and of the Lebesgue space $L^{2}$ . In this paper, which is…

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…
