Abstract

Let be a family of random walks with For ε↓0 under certain conditions the random walk U(∊)n converges to an oscillating random walk. The ladder point distributions and expectations converge correspondingly. Let M = max {U(∊)n, n ≧ 0}, v0 = min {n : U(∊)n = M}, v1 = max {n : U(∊)n = M}. The joint limiting distribution of ∊2σ–2v0 and ∊σ–2M is determined. It is the same as for ∊2σ–2v1 and ∊σ–2M. The marginal ∊σ–2M gives Kingman's heavy traffic theorem. Also lim ∊–1P(M = 0) and lim ∊–1P(M < x) are determined. Proofs are by direct comparison of corresponding probabilities for U(∊)n and for a special family of random walks related to MI/M/1 queues, using the central limit theorem.
