On the influence of cross-diffusion in pattern formation
TL;DR: In this paper, the authors considered the Shigesada-Kawasaki-Teramoto (SKT) model to account for stable inhomogeneous steady states exhibiting spatial segregation, which describe a situation of coexistence of two competing species.
Journal ArticleDOI
Scaling of Saddle-Node Bifurcations: Degeneracies and Rapid Quantitative Changes
TL;DR: In this article, the scaling of the time delay near a "bottleneck" of a generic saddle-node bifurcation is well-known to be given by an inverse square root law.
Journal ArticleDOI
Random switching near bifurcations
Tobias Hurth,Christian Kuehn +1 more
TL;DR: In this article, the interplay between bifurcations and random switching processes of vector fields is studied, and a classification of piecewise-deterministic Markov processes arising from s...
Journal ArticleDOI
From random Poincar\'e maps to stochastic mixed-mode-oscillation patterns
TL;DR: In this article, the effect of Gaussian white noise on fast-slow dynamical systems with one fast and two slow variables, which display mixed-mode oscillations owing to the presence of a folded-node singularity, was quantified.
Journal ArticleDOI
Regularity structures and renormalisation of FitzHugh-Nagumo SPDEs in three space dimensions
Nils Berglund,Christian Kuehn +1 more
TL;DR: In this paper, the authors prove local existence of solutions for a class of suitably renormalised coupled SPDE-ODE systems driven by space-time white noise, where the space dimension is equal to 2 or 3.
