Abstract
Some oscillation criteria are established for the second order nonlinear neutral difference equations of mixed type. where α and β are ratio of odd positive integers with β ≥ 1. Results obtained here generalize some of the results given in the literature. Examples are provided to illustrate the main results. 2010 Mathematics Subject classification: 39A10.
Highlights
1 Introduction In this article, we study the oscillation behavior of solutions of mixed type neutral difference equation of the form, 2(xn + axn−τ1 ± bxn+τ2 )α = qnxβn−σ1 + pnxβx+σ2 where n Î N(n0) = {n0, n0 + 1, ...}, n0 is a nonnegative integer, a, b are real nonnegative constants, τ1, τ2, s1, and s2 are positive integers, {qn} and {pn} are positive real sequences and a, b are ratio of odd positive integers with b ≥ 1
It would be interesting to extend the results of this article to the equation an xn + b xn−τ1 ± c xn+τ2 α = qnxβn−σ1 + pnxγn+σ2 where a, b, and g are ratio of odd positive integers

Summary
We study the oscillation behavior of solutions of mixed type neutral difference equation of the form, 2(xn + axn−τ1 ± bxn+τ2 )α = qnxβn−σ1 + pnxβx+σ2 where n Î N(n0) = {n0, n0 + 1, ...}, n0 is a nonnegative integer, a, b are real nonnegative constants, τ1, τ2, s1, and s2 are positive integers, {qn} and {pn} are positive real sequences and a, b are ratio of odd positive integers with b ≥ 1. A nontrivial solution of Equation (E±) is said to be oscillatory if it is neither eventually positive nor eventually negative.
