A refined Agler decomposition and geometric applications
arXiv:1009.4922 · doi:10.1512/iumj.2011.60.4512
Abstract
We prove a refined Agler decomposition for bounded analytic functions on the bidisk and show how it can be used to reprove an interesting result of Guo et al. related to extending holomorphic functions without increasing their norm. In addition, we give a new treatment of Heath and Suffridge's characterization of holomorphic retracts on the polydisk.
