Oscillation and nonoscillation for difference equations with variable delays Original Research Article

In this paper, we obtain some sharp conditions for oscillation and nonoscillation of the difference equation with variable delays View the MathML source where m is a positive integer, {ki(n)}n=n0∞ and {pi(n)}n=n0∞, (i = 1, 2,…, m) are sequences of positive integers and real numbers, respectively. Our results improve and extend/complement known results in the literature.
