Rigidity of the measurable structure for algebraic actions of higher-rank Abelian groups
We investigate rigidity of measurable structure for higher rank abelian algebraic actions. In particular, we show that ergodic measures for these actions fiber over a 0 entropy measure with Haar measures along the leaves. We deduce various rigidity theorems for isomorphisms and joinings as corollaries.
متن کاملLocal Rigidity of Affine Actions of Higher Rank Groups and Lattices
Let J be a semisimple Lie group with all simple factors of real rank at least two. Let Γ < J be a lattice. We prove a very general local rigidity result about actions of J or Γ. This shows that almost all so-called “standard actions” are locally rigid. As a special case, we see that any action of Γ by toral automorphisms is locally rigid. More generally, given a manifold M on which Γ acts isome...
متن کاملGlobal Rigidity of Higher Rank Anosov Actions on Tori and Nilmanifolds
An Anosov diffeomorphism f on a torus T is affine if f lifts to an affine map on R. By a classical result of Franks and Manning, any Anosov diffeomorphism g on T is topologically conjugate to an affine Anosov diffeomorphism. More precisely, there is a homeomorphism φ : T → T such that f = φ◦g◦φ−1 is an affine Anosov diffeomorphism. We call φ the Franks-Manning conjugacy. The linear part of f is...
متن کاملRigidity of Infinitesimal Momentum Maps
In this paper we prove rigidity theorems for Poisson Lie group actions on Poisson manifolds. In particular, we prove that close infinitesimal momentum maps associated to Poisson Lie group actions are equivalent using a normal form theorem for SCI spaces. When the Poisson structure of the acted manifold is integrable, this yields rigidity also for lifted actions to the symplectic groupoid.
