摘要：
In this paper, we study composition and weighted composition operators that are close to isometries on H2\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${\mathcal {H}}<^>2$$\end{document} but not necessarily isometric. We also obtain a Wold type decomposition for such operators.
