15 صفحه اولMeasures Invariant under the Geodesic Flow and their Projections
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.
متن کاملthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
Geodesic Flow on Polyhedral Surfaces
On a curved surface the front of a point wave evolves in concentric circles which start to overlap and branch after a certain time. This evolution is described by the geodesic ow and helps us to understand the geometry of surfaces. In this paper we compute the evolution of distance circles on polyhedral surfaces and develop a method to visualize the set of circles, their overlapping, branching,...
متن کاملErgodicity 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 (...
