Measurable Rigidity of Actions on Infinite Measure Homogeneous Spaces, Ii
Theorem 1.1 (Shalom and Steger, [21]). Measurable isomorphisms between linear actions on R of abstractly isomorphic lattices in SL2(R) are algebraic. More precisely, if τ : Γ1 ∼= −→Γ2 is an isomorphism between two lattices in SL2(R) and T : R → R is a measure class preserving map with T (γx) = γT (x) for a.e. x ∈ R and all γ ∈ Γ1, then there exists A ∈ GL2(R) so that γ = AγA−1 for all γ ∈ Γ1 an...
متن کاملInvariant Measures and Orbit Closures on Homogeneous Spaces for Actions of Subgroups Generated by Unipotent Elements
The theorems of M. Ratner, describing the finite ergodic invariant measures and the orbit closures for unipotent flows on homogeneous spaces of Lie groups, are extended for actions of subgroups generated by unipotent elements. More precisely: Let G be a Lie group (not necessarily connected) and Γ a closed subgroup of G. Let W be a subgroup of G such that AdG(W ) is contained in the Zariski clos...
متن کاملOn orbits of unipotent flows on homogeneous spaces
Let G be a connected Lie group and let F be a lattice in G (not necessarily co-compact). We show that if («,) is a unipotent one-parameter subgroup of G then every ergodic invariant (locally finite) measure of the action of («,) on G/Y is finite. For 'arithmetic lattices' this was proved in [2]. The present generalization is obtained by studying the 'frequency of visiting compact subsets' for u...

متن کاملProperty (t ) and Rigidity for Actions on Banach Spaces
1.a. Since its introduction by Kazhdan in [Ka], property (T ) became a fundamental concept in mathematics with a wide range of applications to such areas as: • The structure of infinite groups—finite generation and finite Abelianization of higher-rank lattices [Ka], obstruction to free or amalgamated splittings [Wa], [A], [M4], structure of normal subgroups [M2] etc.; • Combinatorics—the first ...
