Abstract: The author considers a periodic competitive multi-species Lotka-Volterra difference  system with variable delays.A sufficient condition is obtained about the existence  of positive periodic solutions of this system by using the method of coincidence degree.

Key words: competitive system, positive periodic solutions, difference equation, coincidence degree
