A measure-conjugacy invariant for free group actions
This paper introduces a new measure-conjugacy invariant for actions of free groups. Using this invariant, it is shown that two Bernoulli shifts over a finitely generated free group are measurably conjugate if and only if their base measures have the same entropy. This answers a question of Ornstein and Weiss.
متن کاملConjugacy, orbit equivalence and classification of measure preserving group actions
We prove that if G is a countable discrete group with property (T) over an infinite subgroup H < G which contains an infinite Abelian subgroup or is normal, then G has continuum many orbit inequivalent measure preserving a.e. free ergodic actions on a standard Borel probability space. Further, we obtain that the measure preserving a.e. free ergodic actions of such a G cannot be classified up to...
متن کاملMeasure Conjugacy Invariants for Actions of Countable Sofic Groups
This paper is motivated by an old and central problem in measurable dynamics: given two dynamical systems, determine whether or not they are measurably conjugate, i.e., isomorphic. Let us set some notation. A dynamical system (or system for short) is a triple (G,X, μ), where (X,μ) is a probability space and G is a group acting by measure-preserving transformations on (X,μ). We will also call th...
متن کاملAlmost Invariant Submanifolds for Compact Group Actions
A compact (not necessarily connected) Lie group G carries a (unique) biinvariant probability measure. Using this measure, one can average orbits of actions of G on affine convex sets to obtain fixed points. In particular, if G acts on a manifoldM , G leaves invariant a riemannian metric onM , and this metric can sometimes be used to obtain fixed points for the nonlinear action of G on M itself....
متن کاملInvariant Polynomials for Multiplicity Free Actions
This work concerns linear multiplicity free actions of the complex groups GC = GL(n,C), GL(n,C) × GL(n,C) and GL(2n,C) on the vector spaces V = Sym(n,C), Mn(C) and Skew(2n,C). We relate the canonical invariants in C[V ⊕ V ∗] to spherical functions for Riemannian symmetric pairs (G,K) where G = GL(n,R), GL(n,C) or GL(n,H) respectively. These in turn can be expressed using three families of class...
