回到台球中的球

Back to balls in billiards

Françoise Pène, Benoit Saussol

摘要:

我们考虑平面上具有周期性凸散射体的台球。这个系统是循环的,在这个意义上,几乎每一个轨道回来任意接近初始点。本文研究了当r->0时,在相空间内,r-球返回到关于初始点的位置所需的时间。我们建立了一个几乎必然收敛速度的存在性,并证明了一个依分布收敛的重新标度的返回时间。

英文摘要:

We consider a billiard in the plane with periodic configuration of convex scatterers. This system is recurrent, in the sense that almost every orbit comes back arbitrarily close to the initial point. In this paper we study the time needed to get back in an r-ball about the initial point, in the phase space and also for the position, in the limit when r->0. We establish the existence of an almost sure convergence rate, and prove a convergence in distribution for the rescaled return times.
