  • Abstract
    with the help of a continuation theorem based on Gaines and Mawhin´s coincidence degree, easily verifiable criteria are established for the global existence of positive periodic solutions of the facultative Lotka-Volterra system with several delays. The result we obtained here generalized the result of Gopalsamy, He (1997), Yang (2002) and Chen (2004).
