A Few Remarks on Periodic Orbits for Planar Billiard Tables
نویسنده
چکیده
I announce a solution of the conjecture about the measure of periodic points for planar billiard tables. The theorem says that if Ω ⊂ R is a compact domain with piecewise C boundary, then the set of periodic orbits for the billiard in Ω has measure zero. Here I outline a proof. A complete version will appear elsewhere.

Three-periodic orbits on hyperbolic plane
Consider what is called the classical (Birkhoff) billiard problem: a particle moves in the planar convex domain D along the straight lines interacting with the boundary ∂D according to the Fermat’s law“ angle of reflection is equal to the angle of incidence”. In mathematical physics it is important to understand how many periodic orbits can be present in a planar billiard. Periodic orbits are t...
متن کاملSome Remarks on Periodic Billiard Orbits in Rational Polygons
A billiard ball, i.e. a point mass, moves inside a polygon Q with unit speed along a straight line until it reaches the boundary ∂Q of the polygon, then instantaneously changes direction according to the mirror law: “the angle of incidence is equal to the angle of reflection,” and continues along the new line (Fig. 1(a)). Despite the simplicity of this description there is much that is unknown ...
متن کاملOn Marked Length Spectrums of Generic Strictly Convex Billiard Tables
In this paper we show that for a generic strictly convex domain, one can recover the eigendata corresponding to Aubry-Mather periodic orbits of the induced billiard map, from the (maximal) marked length spectrums of the domain.

The classical billiard system describes the motion of a point in a plane domain subject to the elastic reflection off the boundary, described by the familiar law of geometrical optics: the angle of incidence equals the angle of reflection; see, e.g., [13, 14] for surveys of mathematical billiards. For every n ≥ 2, the billiard system inside a circle has a very special property: every point of t...
متن کاملPeriodic billiard orbits in right triangles
There is an open set of right triangles such that for each irrational triangle in this set (i) periodic billiards orbits are dense in the phase space, (ii) there is a unique nonsingular perpendicular billiard orbit which is not periodic, and (iii) the perpendicular periodic orbits fill the corresponding invariant surface.
