Pruning, Kneading and Thurston's Classification of Surface Homeomorphisms.
Abstract: In this paper, new techniques for studying the dynamics of families of surface homeomorphisms are introduced. Two
dynamical deformation theories are presented --- one for
surface homeomorphisms, called pruning, and another for graph
endomorphisms, called kneading --- both giving conditions under
which all of the dynamics in an open set can be destroyed,
while leaving the dynamics unchanged elsewhere. These theories
are then used to give a proof of Thurston's classification
theorem for surface homeomorphisms up to isotopy.
