A new isomorphism invariant for actions of free groups
March 28, 3pm; 646 PGH
Abstract
The invariant of the title can be used to completely classify Bernoulli
shifts over free groups. This answers a question of Ornstein and Weiss.
The new invariant is related to the classical Kolmogorov-Sinai entropy
for automorphisms of a Lebesgue space.
