Deformations on Entire Transcendental Functions

Abstract

Given an entire transcendental function f with a non-completely invariant Baker domain, we define a Baker lamination on geodesics to study the divergence and convergence of a pinching process of curves in U. If the boundary of some curve in the Baker lamination of f contains infinity, then the pinching deformation does not converge. On the other hand, if f is semihyperbolic, its Julia set J(f) is thin at infinity, and the lamination does not contain infinity, then the pinching deformation converges uniformly to an entire function F. With this theorem, we prove the existence of an entire function with a wandering domain W to a positive euclidean distance of its postsingular set P(F).
