A discrete map for the dynamics of recurrent excitatory neural networks in the presence of noise

Biosystems, 1998
We 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

1981
Since 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), 2013
We 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

2020
There 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, 2008
Consider 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, 1982
In 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.

Stochastic dynamics of the cubic map: A study of noise-induced transition phenomena

Journal of Statistical Physics, 1983
The effects of finite-amplitude, additive noise on the dynamics generated by a one-dimensional, two-parameter cubic map are considered. The underlying deterministic system exhibits bistability and hysteresis, and noise-induced processes associated with these phenomena are studied. If a bounded noise source is applied to this system, trajectories may be

Effect of noise on the critical golden-mean quasiperiodic dynamics in the circle map

Physica A: Statistical Mechanics and its Applications, 2006
Abstract Scaling regularities are examined associated with effect of additive noise on a critical circle map at the golden-mean rotation number. We present an improved numerical estimate for the scaling constant of Hamm and Graham (Phys. Rev. A46, (1992) 6323) responsible for the effect of noise, γ = 2.3061852653 .
