Escaping sets of continuous functions

Journal d'Analyse Mathématique Aims and scope

Abstract

Our objective is to determine which subsets of ℝd arise as escaping sets of continuous functions from ℝd to itself. We obtain partial answers to this problem, particularly in one dimension, and in the case of open sets. We give a number of examples to show that the situation in one dimension is quite different from the situation in higher dimensions. Our results demonstrate that this problem is both interesting and perhaps surprisingly complicated.
