Isospectral simply-connected homogeneous spaces and the spectral rigidity of group actions
We generalize Sunada’s method to produce new examples of closed, locally non-isometric manifolds which are isospectral. In particular, we produce pairs of isospectral, simplyconnected, locally non-isometric normal homogeneous spaces. These pairs also allow us to see that in general group actions with discrete spectra are not determined up to measurable conjugacy by their spectra. In particular,...
متن کاملInvariants of isospectral deformations and spectral rigidity
We introduce a notion of weak isospectrality for continuous deformations. Let us consider the Laplace-Beltrami operator on a compact Riemannian manifold with boundary with Robin boundary conditions. Given a Kronecker invariant torus Λ of the billiard ball map with a Diophantine vector of rotation we prove that certain integrals on Λ involving the function in the Robin boundary conditions remain...
متن کاملMeasurable 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 کاملHomotopy Categories for Simply Connected Torsion Spaces
For each n > 1 and each multiplicative closed set of integers S, we study closed model category structures on the pointed category of topological spaces, where the class of weak equivalences are classes of maps inducing isomorphism on homotopy groups with coefficients in determined torsion abelian groups, in degrees higher than or equal to n. We take coefficients either on all the cyclic groups...
متن کامل6 On discontinuous group actions on non - Riemannian homogeneous spaces ∗
This article gives an up-to-date account of the theory of discrete group actions on non-Riemannian homogeneous spaces. As an introduction of the motifs of this article, we begin by reviewing the current knowledge of possible global forms of pseudoRiemannian manifolds with constant curvatures, and discuss what kind of problems we propose to pursue. For pseudo-Riemannian manifolds, isometric acti...
