摘要
In a famous paper [8] Hammersley investigated the length L(n) of the longest increasing subsequence of a random n-permutation. Implicit in that paper is a certain one-dimensional continuous-space interacting particle process. By studying a hydrodynamical limit for Hammersley's process we show by fairly ''soft'' arguments that lim n(-1/2)EL(n) = 2. This is a known result, but previous proofs [14, 11] relied on hard analysis of combinatorial asymptotics.
