2011
Electronic Journal of Differential Equations
unpublished
We establish sufficient conditions for the oscillation of all solutions to the second-order impulsive differential equation'r equation' equation'r(t)x (t) ´ + p(t)x (t) + q(t)x(t) + n X i=1 q i (t)|x(t)| α i sgn x(t) = e(t), t = τ k , x(τ k +) = a k x(τ k), x (τ k +) = b k x (τ k). The results obtained in this paper extend some of the existing results and are illustrated by examples.
