Abstract:

 In this paper a general n-species periodic Lotka-Volterra type system with distributed delay and time dependent delay is considered. Sufficient conditions for the existence and global asymptotic stability of positive periodic solutions is established by applying the method of Liapunov functions. These conditions improve and extend the recent ones obtained by Wang, Chen and Lu [2]and Ahlip and King[4].

Key words: Lotka-Volterrasystem, Delay, Positiveperiodicsolution, Globalstability, Lyapunovfunction
