Stability Analysis of a System of Exponential Difference Equations

Discrete Dynamics in Nature and Society, 2014
We study the boundedness character and persistence, existence and uniqueness of positive equilibrium, local and global behavior, and rate of convergence of positive solutions of the following system of exponential difference equations: xn+1=(α1+β1e-xn ...

CALCULATION OF THERMODYNAMIC CHARACTERISTICSOF THE ASCENDING SWIRLING FLOW WITH FIVE SOURCES OF HEATING

Известия высших учебных заведений: Нефть и газ, 2017
Calculations of the thermodynamic characteristics of air flows were carried out when several local sources were heated by the underlying surface. The basic mathematical model is the complete system of Navier-Stokes equations with constant coefficients of

On consistent systems of difference equations [PDF]

Journal of Physics A: Mathematical and Theoretical, 2019
We consider overdetermined systems of difference equations for a single function $u$ which are consistent, and propose a general framework for their analysis. The integrability of such systems is defined as the existence of higher order symmetries in both lattice directions and various examples are presented.

Product-type system of difference equations of second-order solvable in closed form

Electronic Journal of Qualitative Theory of Differential Equations, 2015
This paper presents solutions of the following second-order system of difference equations $$x_{n+1}=\frac{y_n^a}{z_{n-1}^b},\qquad y_{n+1}=\frac{z_n^c}{x_{n-1}^d},\qquad z_{n+1}=\frac{x_n^f}{y_{n-1}^g},\qquad n\in N_0,$$ where $a,b,c,d,f,g\in Z$, and ...

Finite Difference Approximation for Linear Stochastic Partial Differential Equations with Method of Lines [PDF]

A stochastic partial differential equation, or SPDE, describes the dynamics of a stochastic process defined on a space-time continuum. This paper provides a new method for solving SPDEs based on the method of lines (MOL).
