On Oscillation, Convergence and Boundedness of Solutions of Some Nonlinear Difference Equations with multiple Delay

Dinh Cong Huong and Phan Thanh Nam

Abstract.  The oscillation, convergence and boundedness of the solutions of some nonlinear difference equations with multiple delay of the form $$x_{n+1}= G(x_n, x_{n-m_1}, \ldots, x_{n-m_r}), \quad n = 0, 1, \ldots$$ are investigated, where $m_i \in \mathbb{N}_0, \forall i = 1,\ldots,r$ and $G$ is a function mapping $\mathbb R^{m+1}$ to $\mathbb R$.

2000 Mathematics Subject Classification: 39A12.

Keywords: Nonlinear difference equation, multiple delay, oscillation, convergence, boundedness, equilibrium.
