Entropy for actions of free groups under bounded orbit-equivalence

Lewis Bowen, Yuqing Frank Lin

The -invariant is a notion of entropy for probability-measure-preserving actions of free groups. We show it is invariant under bounded orbit-equivalence.

A topological dynamical system with two different positive sofic entropies

Dylan Airey, Lewis Bowen, Frank Lin

A sofic approximation to a countable group is a sequence of partial actions on finite sets that asymptotically approximates the action of the group on itself by left-translations.…

Failure of the pointwise ergodic theorem for

Sofic homological invariants and the Weak Pinsker Property

Lewis Bowen

A probability-measure-preserving transformation has the Weak Pinsker Property (WPP) if for every it is measurably conjugate to the direct product of a transformation with ent…

Superrigidity, measure equivalence, and weak Pinsker entropy

Lewis Bowen, Robin Tucker-Drob

We show that the class , of discrete groups which satisfy the conclusion of Popa's Cocycle Superrigidity Theorem for Bernoulli actions, is invariant under measure equi…

A brief introduction to sofic entropy theory

Lewis Bowen

Sofic entropy theory is a generalization of the classical Kolmogorov-Sinai entropy theory to actions of large class of non-amenable groups called sofic groups. This is a short intr…
