Global attractivity of positive periodic solutions for nonlinear impulsive systems Original Research Article

In this paper, the existence, uniqueness and global attractivity of positive periodic solutions for nonlinear impulsive systems are studied. Firstly, existence conditions are established by the method of lower and upper solutions. Then uniqueness and global attractivity are obtained by developing the theories of monotone and concave operators. And lastly, the method and the results are applied to the impulsive nn-species cooperative Lotka–Volterra system and a model of a single-species dispersal among nn-patches
