Simple closed geodesics

Webb6 dec. 2024 · Let Σ be a compact surface of genus at least 1 with one boundary component, equipped with a hyperbolic metric so that the boundary is geodesic. There is a version of the collar lemma that says there is a collar neighbourhood C of the boundary such that no simple closed geodesic on Σ enters C. WebbWe study simple closed geodesics on a hyperbolic surface of genus g with b geodesic boundary components and c cusps. We show that the number of such geodesics of length at most L is of order L6g+2b+2c−6 . This answers a long-standing open question. Let S be a hyperbolic surface of genus g with c cusps and b boundary components.

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. 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.

In differential geometry and dynamical systems, a closed geodesic on a Riemannian manifold is a geodesic that returns to its starting point with the same tangent direction. It may be formalized as the projection of a closed orbit of the geodesic flow on the tangent space of the manifold.
