Oscillations of second order impulses nonlinear FDE with forcing term

摘要

A kind of second order impulses nonlinear FDE with forcing term is studied in this paper. By means of Kartsatos technique, we reduce it to a second order nonlinear impulsive homogeneous equation. Several criteria on the oscillations of solutions are given. We find some suitable impulse functions such that all the solutions of the equation are oscillatory under the impulse control. At last, we give some examples to demonstrate our results.
