Existence of almost periodic solutions for strong stable impulsive differential equations
1 Bourgas Free University, PO Box 191, Bourgas, Bulgaria
Conditions for strong stability and the existence of almost periodic solutions of systems of impulsive differential equations with impulsive effect at fixed moments are obtained. The investigations are carried out by means of piecewise continuous functions which are analogues of Lyapunov functions.
Keywords: almost periodic solution; impulsive differential equations.
