Ergodicity bounds in the Sliced Wasserstein distance for Schur stable autoregressive processes

Gerardo Barrera, Paulo Henrique da Costa, Michael A. Högele

Explicit calculations in dimension one show for Schur stable autoregressive processes with standard Gaussian noise that the ergodic convergence in the Wasserstein- distance is e…

Weak solutions for coupled reaction-diffusion systems with pattern formation by a stochastic fixed point theorem

Erika Hausenblas, Michael A. Högele, Tesfalem A. Tegegn

Chemical and biochemical reactions can exhibit surprisingly different behaviours, ranging from multiple steady-state solutions to oscillatory solutions and chaotic behaviours. Thes…

Large deviations for light-tailed Lévy bridges on short time scales

Michael A. Högele, Torsten Wetzel

Let be a multivariate Lévy process with Lévy measure for a smoothly regularly varying function of index . The process…

On the tradeoff between almost sure error tolerance and mean deviation frequency in martingale convergence

Luisa F. Estrada, Michael A. Högele, Alexander Steinicke

In this article we quantify almost sure martingale convergence theorems in terms of the tradeoff between asymptotic almost sure rates of convergence (error tolerance) and the respe…

Cut-off phenomenon and asymptotic mixing for multivariate general linear processes

Gerardo Barrera, Michael A. Högele, Pauliina Ilmonen +1

The small noise cut-off phenomenon in continuous time and space has been studied in the recent literature for the linear and non-linear stable Langevin dynamics with additive Lévy…
