Further oscillation criteria for partial difference equations with variable coefficients. (English) Zbl 1189.39011

Summary: Some new oscillation criteria on the oscillation of first-order partial delay difference equations with nonnegative variable coefficients, which improve the recent ones under some additional conditions, are given. Some examples to illustrate the applicability of our results are also supplied of which solutions are plotted by the mathematical programming language Mathematica 7.0.
