## Positive periodic solutions of neutral Lotka-Volterra system with feedback control.(English)Zbl 1125.93031

Summary: 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 neutral Lotka-Volterra system with periodic delays and feedback control. Our results extend and improve existing results, and have further applications in population dynamics.
