在平面二环面中某个台球的轨迹的平均长度
The average length of a trajectory in a certain billiard in a flat two-torus
摘要:
我们从平面二维环面中取出一个小圆盘,并考虑一个点状粒子从圆盘中心开始以线性轨迹运动。我们提供渐近估计的时刻的第一个出口的时间,相对于速度,当半径的光盘趋于零。
英文摘要:
We remove a small disc from the flat two-dimensional torus and consider a point-like particle that starts moving from the center of the disc with linear trajectory. We provide asymptotic estimates for the moments of the first exit time, with respect to the velocity, when the radius of the disc tends to zero.
