Inverse-Positive Matrices and Stability Properties of Linear Stochastic Difference Equations with Aftereffect

open access: yesMathematics
This article examines the stability properties of linear stochastic difference equations with delays. For this purpose, a novel approach is used that combines the theory of inverse-positive matrices and the asymptotic methods developed by N.V.

Stability theory for some scalar finite difference schemes: validity of the modified equations approach* [PDF]

open access: yesESAIM: Proceedings and Surveys, 2021
In this paper, we discuss some limitations of the modified equations approach as a tool for stability analysis for a class of explicit linear schemes to scalar partial differential equations. We show that the infinite series obtained by Fourier transform

Nonlocal Problems for Hilfer Fractional q-Difference Equations

open access: yesFractal and Fractional, 2023
In the paper, we investigate a kind of Hilfer fractional q-difference equations with nonlocal condition. Firstly, the existence and uniqueness results of solutions are obtained by using topological degree theory and Banach fixed point theorem ...

Implicit methods for the simple wave equation [PDF]

open access: yes, 1984
A family of finite difference methods is developed for the numerical solution of the simple wave equation. Local truncation errors are cal- culated for each member of the family and each is analyzed for stability.

On Correctness of Cauchy problem for a Polynomial Difference Operator with Constant Coefficients

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2018
The theory of linear difference equations is applied in various areas of ma\-the\-matics and in the one-dimensional case is quite established. For $n>1$, the situation is much more difficult and even for the constant coefficients a general description of
