Moment equations in a Lotka-Volterra extended system with time correlated noise
D. Valenti, L. Schimansky-Geier, X. Sailer +2
A spatially extended Lotka-Volterra system of two competing species in the presence of two correlated noise sources is analyzed: (i) an external multiplicative time correlated nois…
Moment Equations for a Spatially Extended System of Two Competing Species
D. Valenti, L. Schimansky-Geier, X. Sailer +1
The dynamics of a spatially extended system of two competing species in the presence of two noise sources is studied. A correlated dichotomous noise acts on the interaction paramet…
Noise Induced Complexity: From Subthreshold Oscillations to Spiking in Coupled Excitable Systems
M. Zaks, X. Sailer, L. Schimansky-Geier +1
We study stochastic dynamics of an ensemble of N globally coupled excitable elements. Each element is modeled by a FitzHugh-Nagumo oscillator and is disturbed by independent Gaussi…
Macroscopic limit cycle via pure noise-induced phase transition
R. Kawai, X. Sailer, L. Schimansky-Geier +1
Bistability generated via a pure noise-induced phase transition is reexamined from the view of bifurcations in macroscopic cumulant dynamics. It allows an analytical study of the p…
