Stochastic Nonlinear Waves in all the Right Phases

C. H. S. Hamster

I present an overview of different phases used in the literature to describe the phase of travelling waves in reaction-diffusion equations. The discussion is tailored to understand…

Conditional Speed and Shape Corrections for Travelling Wave Solutions to Stochastically Perturbed Reaction-Diffusion Systems

Mark van den Bosch, Christian H. S. Hamster, Hermen Jan Hupkes

In this work we perform rigorous small noise expansions to study the impact of stochastic forcing on the behaviour of planar travelling wave solutions to reaction-diffusion equatio…

Stability of Travelling Waves on Exponentially Long Timescales in Stochastic Reaction-Diffusion Equations

Christian Hamster, Hermen Jan Hupkes

In this paper we establish the meta-stability of travelling waves for a class of reaction-diffusion equations forced by a multiplicative noise term. In particular, we show that the…

Travelling Waves for Reaction-Diffusion Equations Forced by Translation Invariant Noise

Christian Hamster, Hermen Jan Hupkes

Inspired by applications, we consider reaction-diffusion equations on that are stochastically forced by a small multiplicative noise term that is white in time, colour…

Stability of Traveling Waves for Systems of Reaction-Diffusion Equations with Multiplicative Noise

Christian Hamster, Hermen Jan Hupkes

We consider reaction-diffusion equations that are stochastically forced by a small multiplicative noise term. We show that spectrally stable traveling wave solutions to the determi…
