Almost periodic solutions of nonautonomous Lotka-Volterra competitive systems with dominated delays

In this paper, a class of nonautonomous Lotka-Volterra type multispecies competitive systems with delays is studied. By employing Lyapunov functional, some sufficient conditions to guarantee the existence of almost periodic solutions for the Lotka-Volterra system are obtained.
