Essential curves in handlebodies and topological contractions

Viatcheslav Grines and François Laudenbach

Geometry & Topology 12 (2008) 981–985
Abstract

If X is a compact set, a topological contraction is a self-embedding f such that the intersection of the successive images fk(X), k > 0, consists of one point. In dimension 3, we prove that there are smooth topological contractions of the handlebodies of genus 2 whose image is essential.
