چکیده
Our aim in this paper is to obtain sufficient conditions for the oscillation of every solution of first order difference equations xn+1 − xn + m ∑ i=1 (pixn−ki − qixn−li) = 0, n = 0, 1, 2, ... and xn+1 − xn + m ∑ i=1 (pixn+ki − qixn+li) = 0, n = 0, 1, 2, ... where pi, qi ∈ R and ki, li ∈ N for i = 1, 2, . . . ,m.

متن کاملOscillation Theorems for Second Order Nonlinear Neutral Type Difference Equations with Positive and Negative Coefficients
In this paper, the authors using two inequalities and Ricatti type transformation obtained some new oscillation results for the second order nonlinear neutral type difference equations of the form ∆(an∆(xn + cnxn−k)) + pnf(xn+1−l)− qng(xn+1−m) = 0, and ∆(an∆(xn − cnxn−k)) + pnf(xn+1−l)− qng(xn+1−m) = 0. The obtained results improve, extend and generalize some of the known results. Further examp...
