Some inequalities on the distribution of ladder epochs
Journal of Applied Probability, 1981An algorithm for calculating the probability distribution of ladder epochs is derived. Two theorems are given for bounds on the distribution function of ladder epoch probabilities.

On the moments of ladder epochs for driftless random walks
Journal of Applied Probability, 1994Let X, X1, X2, … be i.i.d. Sn =Σ1 n Xj , E|X| > 0, E(X) = 0 and τ = inf {n ≥ 1: Sn ≥ 0}. By Wald's equation, E(τ) =∞. If E(X 2) <∞, then by a theorem of Burkholder and Gundy (1970), E(τ 1/2) =∞.

On the mean value of the ladder epoch for random walks with a small drift
Izvestiya: Mathematics, 2006In this paper, we prove theorems on the asymptotic behaviour of the mean value of the time at which the non-negative half-axis is first attained for a random walk whose drift tends to zero. It is assumed that the distribution of jumps of the random walk belongs to the domain of attraction of a stable law with exponent .
