We prove the existence of positive periodic solutions for a class of predator prey periodic systems

Battauz, Anna

The coexistence states for periodic planar Kolmogorov systems are studied. The system is limited to the existence of positive T-periodic solutions and to consider a rather general class of systems which generalize some aspects of the characteristic behavior of the predator-prey or the competing species model. A continuation result was used, which is a slightly modified formulation of Lemma 1, where 2D Kolmogorov systems, with N≥1, are considered
