Permanence and global stability of positive solutions of a nonautonomous discrete ratio-dependent predator-prey model. (English) Zbl 1111.39007

The authors consider a two-dimensional system of nonautonomous difference equations, which represent a ratio dependent predator-prey model. Sufficient conditions for permanence of solutions are obtained, and the question of global stability of the positive solutions is studied.
