Abstract :
In this paper, we establish the existence of four positive periodic solutions for the first order differential
system by using the continuation theorem of coincidence degree theory. When our result is applied to
a competition Lotka–Volterra population model, we obtain the existence of four positive periodic solutions
for this model.
