NECESSARY AND SUFFICIENT CONDITIONS FOR OSCILLATIONS OF HIGHER ORDER NEUTRAL DIFFERENCE EQUATIONS WITH SEVERAL DELAYS
Consider the mth order neutral delay difference equation
(*)
where is a positive integer, are positive integers with and We establish necessary and sufficient conditions for oscillation of solutions of the equation (*) for the cases m is odd and m is even. Our results have straightforward extension for advanced difference equations.
