Abstract:

In this paper, the excitable TruscottBrindley dynamical model of the interacting populations under environmental noise is considered. We study a probabilistic mechanism of the noise-induced outbreaks in a zone of stable deterministic equilibria. The stochastic sensitivity functions technique and method of confidence ellipses are applied for the description of the spatial arrangement of random states near the deterministic attractor. The effectiveness of our method for the constructive analysis of the stochastic excitement in TruscottBrindley model is demonstrated. A critical value for the intensity of noise-generating noise-induced outbreaks is estimated.
