Chaotic Itinerancy in Random Dynamical System Related to Associative Memory Models

open access: yesMathematics, 2018
We consider a random dynamical system arising as a model of the behavior of a macrovariable related to a more complicated model of associative memory. This system can be seen as a small (stochastic and deterministic) perturbation of a determinstic system

Classical dilations \`a la Hudson-Parthasarathy of Markov semigroups

open access: yes, 2007
We study the Classical Probability analogue of the dilations of a quantum dynamical semigroup defined in Quantum Probability via quantum stochastic differential equations.

Random cyclic dynamical systems

open access: yesAdvances in Applied Mathematics, 2017
For X a finite subset of the circle and for 0 < r <= 1 fixed, consider the function f_r : X -> X which maps each point to the clockwise furthest element of X within angular distance less than 2 pi r. We study the discrete dynamical system on X generated by f_r, and especially its expected behavior when X is a large random set. We show that, as

Random Dynamical Systems

open access: yes, 2006
The concept of random dynamical system is a comparatively recent development combining ideas and methods from the well developed areas of probability theory and dynamical systems. Due to our inaccurate knowledge of the particular physical system or due to computational or theoretical limitations (lack of sufficient computational power, inefficient ...

Existence of Random Attractors for a p-Laplacian-Type Equation with Additive Noise

open access: yesAbstract and Applied Analysis, 2011
We first establish the existence and uniqueness of a solution for a stochastic p-Laplacian-type equation with additive white noise and show that the unique solution generates a stochastic dynamical system. By using the Dirichlet forms of Laplacian and an

Iterated Function System Models in Data Analysis: Detection and Separation

open access: yes, 2011
We investigate the use of iterated function system (IFS) models for data analysis. An IFS is a discrete dynamical system in which each time step corresponds to the application of one of a finite collection of maps.

On Koopman and Perron-Frobenius operators of random dynamical systems

open access: yesESAIM: Proceedings and Surveys, 2014
In this paper, we investigate the Koopman and the Perron-Frobenius operators of random dynamical systems in general setting. Moreover, we give some necessary and sufficient conditions for the existence of invariant densities for the ...

Roughening of an interface in a system with surface or bulk disorder

open access: yes, 2016
We study numerically the roughening properties of an interface in a two-dimensional Ising model with either random bonds or random fields, which are representative of universality classes where disorder acts only on the interface or also away from it, in
