Measures Invariant under the Geodesic Flow and their Projections
نویسنده
چکیده
Let Sn be the n-sphere of constant positive curvature. For n ≥ 2, we will show that a measure on the unit tangent bundle of S, which is even and invariant under the geodesic flow, is not uniquely determined by its projection to S. Mathematics Subject Classification (2000). 53D25.

Ergodicity of Harmonic Invariant Measures for the Geodesic Flow on Hyperbolic Spaces
The notions of ergodicity (absence of non-trivial invariant sets) and conservativity (absence of non-trivial wandering sets) are basic for the theory of measure preserving transformations. Ergodicity implies conservativity, but the converse is not true in general. Nonetheless, transformations from some classes always happen to be either ergodic (hence, conservative), or completely dissipative (...
متن کاملVariation of the Liouville Measure of a Hyperbolic Surface
For a compact riemannian manifold of negative curvature, the geodesic foliation of its unit tangent bundle is independent of the negatively curved metric, up to Hölder bicontinuous homeomorphism. However, the riemannian metric defines a natural transverse measure to this foliation, the Liouville transverse measure, which does depend on the metric. For a surface S, we show that the map which to ...
متن کاملSemiclassical measures and the Schrödinger flow on compact manifolds
In this article we study limits of Wigner distributions corresponding to sequences of solutions to the Schrödinger equation on a compact Riemannian manifold. After presenting some general results describing their structure, we give an explicit characterization of the set of such limits under an additional geometrical assumption on the manifold; namely, that its geodesic flow is periodic. Finall...
متن کاملAsymptotic Evolution of Smooth Curves under Geodesic Flow on Hyperbolic Manifolds-ii
Extending the earlier results for analytic curve segments, in this article we describe the asymptotic behaviour of evolution of a finite segment of a C-smooth curve under the geodesic flow on the unit tangent bundle of a finite volume hyperbolic n-manifold. In particular, we show that if the curve satisfies certain natural geometric conditions, the pushforward of the parameter measure on the cu...
