Oscillations of Deviating Difference Equations Using an Iterative Method
- 10 Downloads
Oscillation criteria generalizing a series of earlier results are established, for deviating difference equations with non-monotone arguments, based on an iterative method. The results and the improvement achieved over the other known criteria is illustrated by an example, numerically solved in MATLAB.
