A bipartite random mapping TK,L of a finite set V = V1 ? V2, |V1/, = K and /V2/ = L, into itself assigns independently to each i ? V1 its unique image j ? V2 with probability 1/L and to each i ? V2 its unique image j ? V1 with probability 1/K. We study the connected component structure of a random digraph G(TK, L), representing TK, L,, as K ? 8 and L ? 8. We show that, no matter how K and L tend to infinity relative to each other, the joint distribution of the normalized order statistics for the component sizes converges in distribution to the Poisson-Dirichlet distribution on the simplex ? = {{xi}: S xi = 1, xi = xi+1 = 0 for every i = 1}. © 2000 John Wiley & Sons, Inc.
