摘要
Let X-1, X-2,... and Y-1, Y-2,... be two independent sequences of iid Bernoulli random variables with parameter 1/2. Let LCIn be the length of the longest increasing sequence which is a subsequence of both finite sequences X-1,..., X-n and Y-1,..., Y-n. We prove that, as n goes to infinity, n(-1/2)(LCIn - n/2) converges in law to a Brownian functional that we identify.
