Impact of the parametric noise on map-based dynamical systems
AIP Conference Proceedings, 2018Discrete-time nonlinear dynamical systems with general parametric stochastic disturbances are considered. For such systems, a problem of the probabilistic analysis of the random states dispersion around attractors is studied. For the constructive approximation of probabilistic distributions, the method of the stochastic sensitivity is developed. Matrix

Noise-aided control of chaotic dynamics in a logistic map
Physical Review E, 2000Controlling chaos involves employing small perturbations to a control parameter, resulting in the stabilization of the system (naturally chaotic) on one of the infinite unstable periodic orbits embedded in the chaotic attractor. In this Brief Report we study the constructive role of external noise in increasing the efficiency of controlling chaos ...

A discrete map for the dynamics of recurrent excitatory neural networks in the presence of noise
Biosystems, 1998We investigate the effect of the neuron characteristics on the behavior of a recurrent excitatory neural network model. First, we present the different types of dynamics obtained with simulations of a network of coupled excitatory spike-response neuron models placed under the influence of noise. Then, we derive a discrete map describing the dynamics of

Dynamical Systems Described by Discrete Maps with Noise
1981Since this contribution is one of the first in this volume and this conference is a truly interdisciplinary one, it might be useful to begin with a few general comments before entering the more technical part of our contribution.

Mapping noise disturbed oscillators onto quasi-symplectic dynamics
2013 22nd International Conference on Noise and Fluctuations (ICNF), 2013We find exact mappings for a class of limit cycle systems with noise onto quasi-symplectic dynamics, including a van der Pol type oscillator. A dual role potential function is obtained as a component of the quasi-symplectic dynamics. Each component of the quasi-symplectic dynamics has an individual physical meaning and can be measured independently ...

The Simulation of Noise Impact on the Dynamics of a Discrete Chaotic Map
2020There is no clear understanding of the way how a noise influence on nonlinear dynamical systems with chaotic behaviour. Due to difficulties with analysis of real-world chaotic oscillators computer simulation is preferable. However, during the process of simulation, a noise presents too.

Influence of dynamical noise on time series generated by nonlinear maps
Physica D: Nonlinear Phenomena, 2008Consider the dynamical noise called ``pseudonoise'' corrupting a time series generated by a discrete iterated function system (map). Especially, the discrete maps \[ x_{n+1} = f(x_n) \] modified by the two types of maps \[ y_{n+1} = f(y_n) + \eta_n \] or \[ z_{n+1} = f(z_n+\eta_n) \] with noise terms \(\eta_n\) are under consideration.

Symbolic dynamics of one-dimensional maps: Entropies, finite precision, and noise
International Journal of Theoretical Physics, 1982In the study of nonlinear physical systems, one encounters apparently random or chaotic behavior, although the systems may be completely deterministic. Applying techniques from symbolic dynamics to maps of the interval, we compute two measures of chaotic behavior commonly employed in dynamical systems theory: the topological and metric entropies.
