A new class of solvable nonlinear difference equation systems (2110.15619v1)

Abstract: The paper deals with the following system of nonlinear difference equations \begin{equation*} x_{n+1}=ax_{n}^{2}y_{n}+bx_{n}y_{n}^{2},\ y_{n+1}=cx_{n}^{2}y_{n}+dx_{n}y_{n}^{2},\ n\in \mathbb{N}{0}, \end{equation*} where the initial values $x{0},y_{0}$ and the parameters $a$, $b$, $c$, $d$ are arbitrary real numbers, which is a new class of solvable systems of nonlinear difference equations. The general solution of the system is here obtained in closed form via a practical method.
