New title:
             Scaling entropy in ergodic theory and dynamics of metrics


Hopefully the abstract is unchanged.
 
Abstract:
The traditional approach to the theory of dynamical systems is to fix some
metric space (phase space) with the group of homeomorphisms or diffeomorphisms
and to consider evolution of points, functions and measures. The alternative
approach is to fix invariant measure and to study the evolution of metrics. It
happened that such an idea gives the new invariants of dynamics which, for
instance, generalize the Kolmogorov-Sinai entropy and others. In the talk I
describe the first steps in this direction and also classification of the
metric spaces with measure.
