Oscillation of fourth order nonlinear neutral difference equations. II. (English) Zbl 1199.39018
The object of this paper is to study the oscillatory and asymptotic properties of solutions of a class of fourth order nonlinear neutral difference equations. Conditions are derived so that either all solutions are oscillatory or tend to zero or the difference equation admits a positive bounded solution.
For part I, cf. Math. Slovaca 58, No. 2, 221–240 (2008; Zbl 1174.39004).
