On global asymptotic stability of the equilibrium of “predator–prey” system in varying environment

This paper deals with a predator–prey system of differential equations. This ecological system is a model of Lotka–Volterra type whose prey population receives time-variation of the environment. It is not assumed that the time-varying coefficient is weakly integrally positive. We obtain the sifficient conditions of global asymptotic stability of the unique interior equilibrium if the time-variation is bounded.
