旋转遍历和的扩散行为

Diffuse Behaviour of Ergodic Sums Over Rotations

Jean-Pierre Conze, Stefano Isola, Stéphane Le Borgne

摘要:

对于圆上的无理$α$和BV函数$φ$的旋转,我们研究了遍历和$S_L φ(x) := \sum_{j=0}^{L -1} \, φ(x + jα)$的方差。当$α$不是常数类型时,我们构造序列$(L_N)$,使得在某些尺度上,遍历和$S_{L_N} φ$满足ASIP。显式非退化的例子,与应用程序的矩形周期台球在平面上。

英文摘要:

For a rotation by an irrational $α$ on the circle and a BV function $φ$, we study the variance of the ergodic sums $S_L φ(x) := \sum_{j=0}^{L -1} \, φ(x + jα)$. When $α$ is not of constant type, we construct sequences $(L_N)$ such that, at some scale, the ergodic sums $S_{L_N} φ$ satisfy an ASIP. Explicit non-degenerate examples are given, with an application to the rectangular periodic billiard in the plane.
