- Description:
- In this paper we study the oscillation of the difference equations of the form Δ 2 xn+PnΔxn + f(n, Xn-ff, Δx n-h) = 0, in comparison with certain difference equations of order one whose oscillatory character is known. The results can be applied to the difference equation Δ 2 xn+pnΔxn +q n |x-_g|λ|Δxn -h |μ sgnx„-9 = 0, where A and \i are real constants, λ > 0 and μ ≥ 0.
