Central limit theorems for some set partition statistics
We prove the conjectured limiting normality for the number of crossings of a uniformly chosen set partition of [n]={1,2,…,n}. The arguments use a novel stochastic representation and are also used to prove central limit theorems for the dimension index and the number of levels.
