In this paper we consider the second order nonlinear difference equation Γ 4 nondecreasing, and uf u ) 0 as u / 0, q is a real sequence. Some new n Ε½ . sufficient conditions for the oscillation of all solutions of 1 are obtained.
In this paper discrete inequalities are used to offer sufficient conditions for the oscillation of all solutions of the difference equation Ε½ . n n n q 1 n q 1 n where 0 -s prq with p, q odd integers, or p even and q odd integers. Several examples which dwell upon the importance of our results are
## Abstract We give constructive proof of the existence of vanishing at infinity oscillatory solutions for a secondβorder perturbed nonlinear differential equation. In contrast to most results reported in the literature, we do not require oscillatory character of the associated unperturbed equation
