Abstract
|
By the Thurston Stability Theorem, a group of
C1 orientation-preserving diffeomorphisms of the closed unit
interval is locally indicable. We show that the local order structure of
orbits gives a stronger criterion for nonsmoothability that can be used
to produce new examples of locally indicable groups of homeomorphisms of
the interval that are not conjugate to groups of C1
diffeomorphisms.
