Basins of Attraction of Equilibrium Points of Monotone Difference Equations

Sarajevo Journal of Mathematics
We investigate the global character of the difference equation of the form $$ x_{n+1} = f(x_n, x_{n-1},\ldots, x_{n-k+1}), \quadn=0,1, \ldots $$ with several equilibrium points, where $f$ is increasing in all its variables.

Dynamics of an Anti-competitive Two Dimensional Rational System of Difference Equations

Sarajevo Journal of Mathematics
We investigate the global asymptotic behavior of solutions of the following anti-competitive system of rational difference equations\begin{equation*}x_{n+1}=\frac{\gamma _{1}y_{n}}{A_{1}+x_{n}}+h,\quady_{n+1}=\frac{\beta _{2}x_{n}}{A_{2}+y_{n}},\quad n=0,

A Numerical Study of the 3-Periodic Wave Solutions to Toda-Type Equations

Communications in Computational Physics, 2019
In this paper, we present an efficient numerical scheme to calculate Nperiodic wave solutions to the Toda-type equations. The starting point is the algebraic condition for having N-periodic wave solutions proposed by Akira Nakamura.

Period-Two Trichotomies of a Difference Equation of Order Higher Than Two

Sarajevo Journal of Mathematics
We investigate the period-two trichotomies of solutions of the equation $$x_{n+1} = f(x_{n}, x_{n-1},x_{n-2}), \quad n=0, 1, \ldots $$ where the function $f$ satisfies certain monotonicity conditions.
