Initial data stability and admissibility of spaces for Itô linear difference equations [PDF]

open access: yes, 2017
summary:The admissibility of spaces for Itô functional difference equations is investigated by the method of modeling equations. The problem of space admissibility is closely connected with the initial data stability problem of solutions for Itô delay ...

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.

Dynamics and Solutions of Higher-Order Difference Equations

open access: yes, 2023
The invariance method, known as Lie analysis, consists of finding a group of transformations that leave a difference equation invariant. This powerful tool permits one to lower the order, linearize and more importantly, obtain analytical solutions of ...

Riccati equations in stability theory of difference equations with memory [PDF]

open access: yes1999 European Control Conference (ECC), 1999
This paper defines several Riccati equations that allow checking the stability of difference equations with delay effect as x i+1 = mΣ j=0 A j x i-j (x i ∊ Rn). These various matrix Riccati equations have the same dimension n than the vector x, whatever the order m may be: this represents an advantage for high orders m when compared to classical ...

Stability problem of some nonlinear difference equations

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1998
In this paper, we investigate the asymptotic stability of the recursive sequence xn+1=α+βxn21+γxn−1,    n=0,1,… and the existence of certain monotonic solutions of the equation xn+1=xnpf(xn,xn−1,…,xn−k),     n=0,1,… which includes as a special case the ...

Global Asymptotic Stability of a Nonautonomous Difference Equation [PDF]

open access: yesJournal of Applied Mathematics, 2014
We study the following nonautonomous difference equation:xn+1=(xnxn-1+pn)/(xn+xn-1),n=0,1,…, wherepn>0is a period-2 sequence and the initial valuesx-1,x0∈(0,∞). We show that the unique prime period-2 solution of the equation above is globally asymptotically stable.
