Oscillatory and asymptotic behaviour of perturbed quasilinear second order difference equations

Ethiraju Thandapani, L. Ramuppillai (1998)

Archivum Mathematicum

Similarity:

This paper deals with oscillatory and asymptotic behaviour of solutions of second order quasilinear difference equation of the form $Δ (a_{n - 1} | Δ y_{n - 1} |^{α - 1} Δ y_{n - 1}) + F (n, y_{n}) = G (n, y_{n}, Δ y_{n}), n \in N (n_{0}) (E)$ where $α > 0$ . Some sufficient conditions for all solutions of (E) to be oscillatory are obtained. Asymptotic behaviour of nonoscillatory solutions of (E) are also considered.

Some new oscillation and nonoscillation criteria for the second order neutral delay difference equation $Δ (c_{n} Δ (y_{n} + p_{n} y_{n - k})) + q_{n} y_{n + 1 - m}^{β} = 0, n \geq n_{0}$ where $k$ , $m$ are positive integers and $β$ is a ratio of odd positive integers are established, under the condition $\sum_{n = n_{0}}^{\infty} \frac{1}{c_{n}} < \infty .$
