Four periodic solutions of a generalized delayed predator–prey system. (English) Zbl 1112.34048

This paper is concerned with the existence of multiple positive periodic solutions of a two-predator and one-prey system in which the distributed delay, periodic discrete delay and nonmonotone function response are incorported. By using the continuation theorem of coincidence degree theory, a sufficient condition is given to establish the existence of four positive periodic solutions.
