Discrete & Continuous Dynamical Systems - B, 2021 <p style='text-indent:20px;'>Effect of additive fading noise on a behavior of the solution of a stochastic difference equation with continuous time is investigated. It is shown that if the zero solution of the initial stochastic difference equation is asymptotically mean square quasistable and the level of additive stochastic perturbations is ...

Additive difference scheme for two-dimensional fractional in time diffusion equation
Filomat, 2017 An additive finite-difference scheme for numerical approximation of initial-boundary value problem for two-dimensional fractional in time diffusion equation is proposed. Its stability is investigated and a convergence rate estimate is obtained.

Exponential dichotomy for noninvertible linear difference equations [PDF]
Journal of difference equations and applications (Print), 2021 In this article we study exponential dichotomies for noninvertible linear difference equations in finite dimensions. After giving the definition, we study the extent to which the projection in a dichotomy is unique.

Novel structure-preserving schemes for stochastic Klein-Gordon-Schrödinger equations with additive noise [PDF]
Journal of Computational Physics, 2023 Stochastic Klein--Gordon--Schr\"odinger (KGS) equations are important mathematical models and describe the interaction between scalar nucleons and neutral scalar mesons in the stochastic environment.

MULTISPECTRAL IMAGE RESTORATION USING A VECTOR-VALUED REACTION-DIFFUSION BASED MIXED NOISE REMOVAL TECHNIQUE [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2023 A novel multispectral image filtering technique is proposed in this article. Since the multispectral images are often corrupted by mixed Poisson-Gaussian noise during the sensing and acquisition process, a nonlinear anisotropic diffusion-based ...

Simultaneous Additive Equations: Repeated and Differing Degrees [PDF]
Canadian Journal of Mathematics, 2017 Abstract We obtain bounds for the number of variables required to establish Hasse principles, both for the existence of solutions and for asymptotic formulæ, for systems of additive equations containing forms of differing degree but also multiple forms of like degree.
