Dynamics of a discrete predator-prey system with nonconstant death rate

In this paper, we will consider a discrete non-autonomous predator-prey system with nonconstant death rate. We give sufficient conditions in order to get a dissipative and permanent system. By using the continuation theorem based on Gaines and Mawhin's coincidence degree, we study the existence...
