On the Euler discretization error of Brownian motion about random times

A. B. Dieker, Guido Lagos

In this paper we derive weak limits for the discretization errors of sampling barrier-hitting and extreme events of Brownian motion by using the Euler discretization simulation met…

A Dichotomy for Sampling Barrier-Crossing Events of Random Walks with Regularly Varying Tails

Ton Dieker, Guido Lagos

We study how to sample paths of a random walk up to the first time it crosses a fixed barrier, in the setting where the step sizes are iid with negative mean and have a regularly v…

Spectral analysis of random-to-random Markov chains

A. B. Dieker, Franco Saliola

We compute the eigenvalues and eigenspaces of random-to-random Markov chains. We use a family of maps which reveal a remarkable recursive structure of the eigenspaces, yielding an…

Stochastic billiards for sampling from the boundary of a convex set

A. B. Dieker, Santosh Vempala

Stochastic billiards can be used for approximate sampling from the boundary of a bounded convex set through the Markov Chain Monte Carlo (MCMC) paradigm. This paper studies how man…

Exact simulation of Brown-Resnick random fields at a finite number of locations

A. B. Dieker, T. Mikosch

We propose an exact simulation method for Brown-Resnick random fields, building on new representations for these stationary max-stable fields. The main idea is to apply suitable ch…

Validity of heavy-traffic steady-state approximations in many-server queues with abandonment

J. G. Dai, A. B. Dieker, Xuefeng Gao

We consider GI/Ph/n+M parallel-server systems with a renewal arrival process, a phase-type service time distribution, n homogenous servers, and an exponential patience time distrib…
