On positive solutions of the Lotka–Volterra cooperating models with diffusion Original Research Article

In this paper, using the existence and comparison conclusion for the time-periodic quasimonotone nondecreasing systems given by Pao C.V. and iterative method, we investigate the time-periodic Lotka–Volterra cooperating model and present some existence, uniqueness and nonexistence results. We also use similar methods to treat the corresponding stationary system to give parallel results.
