【Abstract】 The existence of the positive solutions of a nonautonomous predator- prey system with Crowley-Martin functional response is explored. In the periodic case, the existence of a positive periodic solution and a boundary periodic solution for this system are established with the help of a continuation theorem in coincidence degree theory. Especially, some numerical simulations are carried out to illustrate our mathematical findings.更多还原
