Hilbert-Schmidtness of the $M_{θ, φ}$ -type submodules

Chao Zu, Yufeng Lu

Let $θ (z), φ (w)$ be two nonconstant inner functions and $M$ be a submodule in $H^{2} (D^{2})$ . Let $C_{θ, φ}$ denote the composition operator on $H^{2} (D^{2})$ defined by $C…

Notes on a special order on $Z^{\infty}$

Jiawei Sun, Chao Zu, Yufeng Lu

In 1958, Helson and Lowdenslager extended the theory of analytic functions to a general class of groups with ordered duals. In this context, analytic functions on such a group $G$ …
