递减细分过程

The diminishing segment process

Gergely Ambrus, Péter Kevei, Viktor Vígh

摘要:

设S(1)是线段[-1,1],并以如下方式递归地定义线段S(n):设S(n+1)是S(n)和a(n+1)+ S(1)的交集,其中点a(n+1)是在线段S(n)上随机选择的,具有均匀分布。对于S(n)的半径r(n),我们证明了n(r(n)-1//2)按分布收敛于一个指数律,并证明了极限单位区间的中心服从反正弦分布.

英文摘要:

Let S(1) be the segment [-1,1], and define the segments S(n) recursively in the following manner: let S(n+1) be the intersection of S(n) and a(n+1) + S(1), where the point a(n+1) is chosen randomly on the segment S(n) with uniform distribution. For the radius r(n) of S(n) we prove that n(r(n) - 1//2) converges in distribution to an exponential law, and we also show that the centre of the limiting unit interval has arcsine distribution.
