Webb12 mars 2013 · We investigate the relationship, in various contexts, between a closed geodesic with self-intersection number k(for brevity, called a k-geodesic) and its length. We show that for a fixed compact hyperbolic surface, the short k-geodesics have length comparable with the square root of k.

Webb1 jan. 1999 · Non-compact manifolds do not necessarily contain closed geodesics, Euclidean space being an obvious example. Even if the manifold is not simply connected, it may not contain any simple closed geodesics, as with the hyperbolic thrice-punctured sphere. However, among the orientable, finite area, complete hyperbolic 2-manifolds, the … WebbWe show that the number of square-tiled surfaces of genus , with marked points, with one or both of its horizontal and vertical foliations belonging to fixed mapping class group orbits, and having at most squares, is… WebbPogorelov proved in 1949 that every convex polyhedron has at least three simple closed quasigeodesics. Whereas a geodesic has exactly a π surface angle to either side at each point, a quasigeodesic has at most a π surface angle to either side at each point.

WebbEvidently no closed geodesic may cross though there are closed geodesics which approach arbitrarily close. This second observation is no longer true if we restrict to simple geodesics. That is, as was observed by Haas [H], there is a collar (i.e. a regular neighborhood) around which meets no other closed simple geodesic; we call the …

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.
