The Exit Problem from a Neighborhood of the Global Attractor for Dynamical Systems Perturbed by Heavy-Tailed Lévy Processes

Abstract: We consider a finite dimensional deterministic dynamical system with a global attractor A with a unique ergodic measure P concentrated on it, which is uniformly parametrized by the mean of the trajectories in a bounded set D containing A. We perturbe this dynamical system by a multiplicative heavy tailed Lévy noise of small intensity ε > 0 and solve the asymptotic first exit time and location problem from a bounded domain D around the attractor A in the limit of ε ց 0. In contrast to the case of Gaussian pertu… Show more

“…The analysis of the relation between the frequency and the size of the large jumps justifies the assumption of a bistable model given by equations of type (1). This gave rise to further studies of a great variety of such models [10], [13], [16], [17] and [18]. In [8] and [9] the authors solve the corresponding model selection problem within the class of α-stable diffusions based on a fine analysis of sample path properties.…”

“…All these approaches yield exponential exit rates on the precise noise dependence. Further recent results on the first exit and metastability of Lévy driven systems in finite and infinite dimensions were obtained by Imkeller and Pavlyukevich (2006a); Pavlyukevich (2011); Debussche et al (2013); Högele and Pavlyukevich (2013). It is worth mentioning that in the case of an overdamped particle subject to ε-small α-stable noise, α P p0, 2q, the expected exit time behaves polynomially…”
