A Beurling Theorem for Generalized Hardy Spaces on a Multiply Connected Domain
Yanni Chen, Don Hadwin, Zhe Liu +1
The object of this paper is to prove a version of the Beurling-Helson-Lowdenslager invariant subspace theorem for operators on certain Banach spaces of functions on a multiply conn…
A non-commutative Beurling's theorem with respect to unitarily invariant norms
Yanni Chen, Don Hadwin, Junhao Shen
In 1967, Arveson invented a non-commutative generalization of classical known as finite maximal subdiagonal subalgebras, for a finite von Neumann algebra …
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 and of the Lebesgue space . In this paper, which is…
A note on linear approximately orthogonality preserving mappings
Ye Zhang, Yanni Chen, Don Hadwin +1
In this paper, linear -orthogonality preserving mappings are studied. We define as the smallest for which is $\var…
Lebesgue and Hardy Spaces for Symmetric Norms II: A Vector-Valued Beurling Theorem
Yanni Chen, Don Hadwin, Ye Zhang
Suppose is a rotationally symmetric norm on and is a "nice" norm on where is a -finite measure on…
Lebesgue and Hardy spaces for symmetric norms I
Yanni Chen
In this paper, we define and study a class of norms on , called , which properly…
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 is a nonseparable Hilbert space and is any closed ideal in that is not…
