A new result on the exponential stability of solutions of non-linear neutral type periodic systems with variable delay.

In this work, we consider a nonlinear time-varying delay system of neutral type differential equations with periodic coefficients and we obtain new sufficient conditions to ensure exponentially stability of zero solution of this system. The Lyapunov-Krasovskii functional approach is useful as a basic tool to prove the main general result of this paper. [ABSTRACT FROM AUTHOR]
