 There exists an astonishingly simple formula for the dynamical entropy of a process
(measure-preserving transformation with a partition),which can be easily extended
to actions of any countable group. This formula coincides with the standard one up
to amenable groups. I will discuss its applicability to other groups and, exploring
another direction, to topological entropy.
