Norms of composition operators with rational symbol

[摘要] We compute the norms of composition operators with rational symbols that satisfy certain properties, extending Christopher Hammond's methods on operators with linear fractional symbols. This leads to a host of new examples of composition operators whose norms are calculable. (c) 2006 Elsevier Inc. All rights reserved.
