Lyapunov Exponent Estimates of a Class of Higher-order Stochastic Anderson Models
نویسندگان
چکیده
In this article, we propose a class of high-order stochastic partial differential equations (SPDEs) for spatial dimensions d ≤ 5 which might be called high-order stochastic Anderson models. This class of the equations is perturbed by a space-time white noise when d ≤ 3 and by a space-correlated Gaussian noise when d = 4, 5. The objectives of this article are to get some estimates on the Lyapunov exponent of the solutions and to study the convergence rates of the chaos expansions of the solutions for the models.

Perturbative test of single parameter scaling for 1D random media
Products of random matrices associated to one-dimensional random media satisfy a central limit theorem assuring convergence to a gaussian centered at the Lyapunov exponent. The hypothesis of single parameter scaling states that its variance is equal to the Lyapunov exponent. We settle discussions about its validity for a wide class of models by proving that, away from anomalies, single paramete...
متن کاملLyapunov Exponents for Stochastic Anderson Models with Non-gaussian Noise
The stochastic Anderson model in discrete or continuous space is defined for a class of non-Gaussian space-time potentials W as solutions u to the multiplicative stochastic heat equation u(t, x) = 1 + ∫ t 0 κ∆u(s, x)ds+ ∫ t 0 βW (ds, x)u(s, x) with diffusivity κ and inverse-temperature β. The relation with the corresponding polymer model in a random environment is given. The large time exponent...
متن کاملStability of two classes of improved backward Euler methods for stochastic delay differential equations of neutral type
This paper examines stability analysis of two classes of improved backward Euler methods, namely split-step $(theta, lambda)$-backward Euler (SSBE) and semi-implicit $(theta,lambda)$-Euler (SIE) methods, for nonlinear neutral stochastic delay differential equations (NSDDEs). It is proved that the SSBE method with $theta, lambdain(0,1]$ can recover the exponential mean-square stability with some...
متن کاملInvestigating Chaos in Tehran Stock Exchange Index
Modeling and analysis of future prices has been hot topic for economic analysts in recent years. Traditionally, the complex movements in the prices are usually taken as random or stochastic process. However, they may be produced by a deterministic nonlinear process. Accuracy and efficiency of economic models in the short period forecasting is strategic and crucial for business world. Nonlinear ...
متن کاملEvaluation of Lyapunov exponent in generalized linear dynamical models of queueing networks
The problem of evaluation of Lyapunov exponent in queueing network analysis is considered based on models and methods of idempotent algebra. General existence conditions for Lyapunov exponent to exist in generalized linear stochastic dynamic systems are given, and examples of evaluation of the exponent for systems with matrices of particular types are presented. A method which allow one to get ...
