Stamov, Gani Tr.; Petrov, Nikolay Lyapunov-Razumikhin method for existence of almost periodic solutions of impulsive differential-difference equations. (English) Zbl 1156.34057 Nonlinear Stud. 15, No. 2, 151-161 (2008). Summary: Sufficient conditions about the existence of almost periodic solutions of systems of impulsive differential-difference equations are obtained. The investigations are carried out by means of piecewise continuous Lyapunov functions and Razumikhin techniques.
