WebbWe can de ne the word length of a closed geodesic by j j= inffk: [ ] = [g 1g k] with g 1; g k2 g where [ 1] denotes the conjugacy class. Another classical result, a consequence of a deeper result of Milnor, is that the word length and … Webbin nitely many closed geodesics. On the other hand, for a given upper bound on the length, the number of closed geodesics is usually nite. M. Mirzakhani [18] showed that the …

We prove a … Webb12 apr. 2024 · Find parametric equations for a simple closed curve of length 4π on the unit sphere which minimizes the mean spherical distance from the curve to the sphere; the solution must include proof of minimization. Can you solve this problem with arbitrary L > 2π instead of 4π? There seems to be little precedent for this problem.

If the values of the … WebbIn such a curved space, the shortest path between two points is known as a geodesic. For example, on a sphere the geodesic is a great circle. Mirzakhani’s research involved calculating the number of a certain type of geodesic, called simple closed geodesics, on hyperbolic surfaces.
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
