In the multi-urn Ehrenfest model $N$ balls are distributed among $d + 1 (d \geqq 2)$ urns. If we label the urns $0, 1, \cdots, d,$ then the system is ... d)$ when there are $i_j$ balls in urn $j (j = 1, 2, \cdots, d)$ and $N - \mathbf{1}\cdot\mathbf{i}$ balls in urn 0.

We propose a two-urn model of Pólya type as follows. There are two urns, urn A and urn B . At the beginning, urn A contains r A red and w A white balls and urn B contains r B red and w B white balls. We first draw m balls from urn A and note their colors, say i red ... i white balls. The balls are returned to urn A and bi red and b ( m - i ) white balls are added to urn B . Next, we draw ℓ balls from urn ...

We study a class of balanced urn schemes on balls of two colors (say white and black). At each drawing, a sample of size m≥1 is taken out from the urn, and ball addition rules are applied. We consider ... several earlier works focused on special cases of urn models with multiple drawings [5], [6], [17], [19], [ ... size. We categorize the class into small-index urns (Λ 12), and triangular urns. We obtain central limit theorems for small- and critical-index urns and prove almost-sure convergence for triangular and ...
