WebbTheorem 1.1 The set of surfaces with simple simple length spectrum is dense and its complement is Baire meagre. If A is a path in Teichmüller space T then there is a surface on A which has at least two distinct simple closed geodesics of the same length. Let E denote the set of all surfaces with at least one pair of simple closed geodesics of WebbThe discrete geodesic flow on Nagao lattice quotient of the space of bi-infinite geodesics in regular trees can be viewed as the right diagonal action on the double quotient of PGL2Fq((t−1)) by PGL2Fq[t] and PGL2(Fq[[t−1]]). We investigate the measure-theoretic entropy of the discrete geodesic flow with respect to invariant probability measures. fi nano website

WebbThe single closed geodesic is the image (under quotient) of the y -axis. Take any other geodesic which limits to 0 and push it down under the covering map; it will spiral in from … WebbThe question of existence of c10sed geodesics on a Riemannian manifold and the properties of the corresponding periodic orbits in the geodesic flow has been the object of intensive investigations since the beginning of global differential geo metry during the last century. The simplest case occurs for c10sed surfaces of negative curvature. Here, the … Webbgeodesic current with length measure gives an invariant measure for the geodesic flow. Remark. The geodesic flow cannot be reconstructed from the topological action of Γ on S1, since its time parameterization determines the lengths of closed geodesics. Intersection number.
