WebbEvery isotopy class of asimple closed curve contains a unique simple closed geodesic on X. Two simpleclosed geodesics γ1and γ2are of the same type if and only if there existsg ∈ Modg,nsuch that g · γ1= γ2. The type of a simple closed geodesic γ isdetermined by the topology of Sg,n (γ), the surface that we get by cutting Sg,nalong γ. 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.

Webb15 aug. 2014 · The prime geodesic theorem (of Margulis?) states that on a compact surface of (constant?) negative curvature, the number of prime closed geodesics of length at most L = log x is approximately e L / L = x / log x as x grows. This is commonly viewed as an analogue of the prime number theorem.
