A Gleason-Kahane-Żelazko theorem for reproducing kernel Hilbert spaces

Cheng Chu, Michael Hartz, Javad Mashreghi +1

We establish the following Hilbert-space analogue of the Gleason-Kahane-Żelazko theorem. If is a reproducing kernel Hilbert space with a normalized complete Pick kern…

Product of truncated Hankel and truncated Toeplitz operators

Cheng Chu

A truncated Toeplitz operator is the compression of a classical Toeplitz operator on the Hardy space to a model space. A truncated Hankel operator is the compression of a Hankel op…

Which de Branges-Rovnyak spaces have complete Nevanlinna-Pick property?

Cheng Chu

We characterize the de Branges-Rovnyak spaces with complete Nevanlinna-Pick property. Our method relies on the general theory of reproducing kernel Hilbert spaces.

Hilbert Spaces Contractively Contained in Weighted Bergman Spaces on the Unit Disk

Cheng Chu

Sub-Bergman Hilbert spaces are analogues of de Branges-Rovnyak spaces in the Bergman space setting. They are reproducing kernel Hilbert spaces contractively contained in the Bergma…

Density of Polynomials in Sub-Bergman Hilbert Spaces

Cheng Chu

The sub-Bergman Hilbert spaces are analogues of de BrangesRovnyak spaces in the Bergman space setting. We prove that the polynomials are dense in sub-Bergman Hilbert spaces. This a…
