The existence and permanence of the positive solutions for a one-prey and two-predators model with Crowley-Martin type functional response are considered. First
the bifurcation from a double eigenvalue for system is discussed by virtue of the space decomposition and the implicit function theorem
and the sufficient conditions for the existence of the positive steady-state solutions are obtained. Moreover
the sufficient conditions for the non-existence of the positive steady-state solutions are given. Finally
asymptotic behavior of the positive solutions of the parabolic system is investigated
and the sufficient conditions for extinction and permanence of the parabolic system are given by using the comparison theorem.
