Difference equations with impulses

Difference equations with impulses are studied focussing on the existence of periodic or bounded orbits, asymptotic behavior and chaos. So impulses are used to control the dynamics of the autonomous difference equations. A model of supply and demand is also considered when Li-Yorke chaos is shown among others

Chaos suppression via periodic pulses in a class of piece-wise continuous systems

AbstractIn this paper, we prove that an existing algorithm with periodical impulses for chaos suppression in continuous systems can be further extended and successfully applied to a class of piecewise continuous systems. For this purpose, the underlying initial value problem is transformed into a continuous problem via Filippov regularization and Cellina’s approximation theorem. Next, some results on existence and continuation for ODEs with impulses are applied. As an example, the piece-wise continuous Chen system is considered
