Let a 0 and a 1 be two matrices in SL(2, \({\mathbb{Z}}\)) which span a non-solvable group. Let x 0 be an irrational point on the torus \({\mathbb{T}^2}\). We toss a 0 or a 1, apply it to x 0, get another irrational point x 1, do it again to x 1, get a point x 2, and again. This random trajectory is equidistributed on the torus. This phenomenon is quite general on any finite volume homogeneous space.

齐次空间随机游动简介

一个 0一个 1在SL两个矩阵(2,\({\ mathbb {Z}} \) ),其跨越非解群。令x 0为圆环\({\ mathbb {T} ^ 2} \)上的一个非理性点。我们折腾一个 0一个 1,将它应用于X 0,再弄点不合理X 1,做一遍,以X 1,拿到一分X 2,和一次。该随机轨迹在圆环上均匀分布。这种现象在任何有限体积的均匀空间上都是很普遍的。
