Sufficient Conditions for the Oscillation of Linear Delay Difference Equations with Oscillating Coefficients

AbstractIn this paper sufficient conditions for the oscillation of all solutions of the delay difference equation xn+1−xn+pnxn−k=0, n=0,1,2,…, are established, where the coefficient pn itself may be allowed to be oscillatory. We also give an example to demonstrate the advantage of our results
