| dc.description | We consider the simplest split-merge Markov operator $T$ on the infinite-dimensional simplex $Σ_1$ of monotone non-negative sequences with unit sum. For a sequence $x\inΣ_1$, it picks a size-biased sample (with replacement) of two elements of $x$; if these elements are distinct, it merges them and reorders the sequence, and if the same element is picked twice, it splits this element uniformly into two parts and reorders the sequence. We prove that the means along the $T$-trajectory of the $\de$-measure at the vector $(1,0,0,{...})$ converge to the Poisson--Dirichlet distribution PD(1). | |
