| Abstract: |
In this paper, we study oscillation and nonoscillation behaviour of the second order nonlinear difference equations of the form Δ (r_n ψ (x_n) Δ x_n)+ q_ n+ 1 f (x_ n+ 1)= 0, n ∈ N (n_o), and Δ (r_n ψ (x_n) Δ x_n)+ q_n f (n, x_n)= 0, n ∈ N (n_o), where N (no)= no, no+ 1,…,(no is a fixed nonnegative integer number), Δx n= xn+ 1− xn is the forward difference operator, x: N (no)→ ℝ, r: N (no)→(0,∞), Ψ: ℝ→(0,∞), f is a real valued continuous function, and qn is a sequence of real valued. |
