On the spectrum of stochastic perturbations of the shift and Julia sets
(Polish Acad Sciences Inst Mathematics, 2012-01-01)
We extend the Killeen-Taylor study [Nonlinearity 13 (2000)] by investigating in different Banach spaces (l(alpha)(N), c(0)(N),c(N)) the point, continuous and residual spectra of stochastic perturbations of the shift operator ...

Decomposition of stochastic flow and an averaging principle for slow perturbations
(2020-01-01)
In this work we use the stochastic flow decomposition technique to get components that represent the dynamics of the slow and fast motion of a stochastic differential equation with a random perturbation. Assuming a Lipschitz ...

Metastability for small random perturbations of a PDE with blow-up
(Elsevier Science, 2018-05)
We study random perturbations of a reaction–diffusion equation with a unique stable equilibrium and solutions that blow-up in finite time. If the strength of the perturbation ε>0 is small and the initial data is in the ...
Stability region and radius in electric power systems under sustained random perturbations
(Elsevier, 2015)
Two concepts are proposed to characterize the behavior of stochastic systems under sustained random perturbations in time: Using Lyapunov exponents we define the region where an electric power system can be operated under ...
Stochastic perturbations of convex billiards
(IOP Publishing, 2015-11)
We consider a strictly convex billiard table with C 2 boundary, with the dynamics subjected to random perturbations. Each time the billiard ball hits the boundary its reflection angle has a random perturbation. The ...
Random perturbations of stochastic processes with unbounded variable length memory
(UNIV WASHINGTON, DEPT MATHEMATICS, 2008)
We consider binary infinite order stochastic chains perturbed by a random noise. This means that at each time step, the value assumed by the chain can be randomly and independently flipped with a small fixed probability. ...
Robustness of the non-Markovian Alzheimer walk under stochastic perturbation
(EPL ASSOCIATION, EUROPEAN PHYSICAL SOCIETYMULHOUSE, 2012)
The elephant walk model originally proposed by Schutz and Trimper to investigate non-Markovian processes led to the investigation of a series of other random-walk models. Of these, the best known is the Alzheimer walk ...
