Dynamical Systems and Ergodic Theory

Constructions
in Smooth Ergodic Theory
Given a collection of dynamical properties is it possible to find a
smooth map, possibly a diffeomorphism, of a compact manifold which
exhibits these properties. Ideally we seek obstructions to being able
to find any smooth model of a given collection of properties. For
actions of Z the only known obstruction is infinite entropy.

Dynamical
Cohomology
Additive cohomology classes determine the asymptotic behaviour of
Birkhoff sums and are crucial in studying diverse problems including
special flows and ergodic optimization. Mutiplicative cohomology
classes are crucial in various problems involving skew products and
special flows. Studying such equations over Anosov systems is the
content of Livic Theory.
