摘要

Let X1,X2,...,Xn,...X_1, X_2, ..., X_n, ... be a sequence of iid random variables with values in a finite alphabet {1,...,m}\{1,...,m\}. Let LInLI_n be the length of the longest increasing subsequence of X1,X2,...,Xn.X_1, X_2, ..., X_n. We express the limiting distribution of LInLI_n as functionals of mm and (m1)(m-1)-dimensional Brownian motions. These expressions are then related to similar functionals appearing in queueing theory, allowing us to further establish asymptotic behaviors as mm grows. The finite alphabet results are then used to treat the countable (infinite) alphabet.
