On the complexity of proper holomorphic mappings between balls

Complex Variables 2009-06-01 v3

Abstract

We make several new contributions to the study of proper holomorphic mappings between balls. Our results include a degree estimate for rational proper maps, a new gap phenomenon for convex families of arbitrary proper maps, and an interesting result about inverse images.
