Abstract:
This paper discusses relationships among the basic notions
that have been important in recent investigations of
the ergodicity of volume-preserving
partially hyperbolic diffeomorphisms. In particular we survey the possible definitions
of dynamical coherence and discuss the relationship between dynamical coherence and center bunching.
