Global dynamics of three-dimensional Lotka-Volterra competition models with seasonal succession: II. Uniqueness of positive fixed points

Lei Niu, Yi Wang, Xizhuang Xie

In this second part of the series, we investigate the uniqueness of positive fixed points of the Poincare map associated with the 3-dimensional Lotka-Volterra competition model wit…

Classification of permanence and impermanence for a Lotka-Volterra model of three competing species with seasonal succession

Lei Niu, Xizhuang Xie

In this paper, we are concerned with the permanence of a Lotka-Volterra model of three competing species with seasonal succession. Based on the existence of a carrying simplex, tha…

Global dynamics of three-dimensional Lotka-Volterra competition models with seasonal succession: I. Classification of dynamics

Lei Niu, Yi Wang, Xizhuang Xie

The current series of two papers focus on a 3-dimensional Lotka-Volterra competition model of differential equations with seasonal succession, which exhibits that populations exper…

Generic Poincaré-Bendixson Theorem for singularly perturbed monotone systems with respect to cones of rank-

Lin Niu, Xizhuang Xie

We investigate the singularly perturbed monotone systems with respect to cones of rank and obtain the so called Generic Poincaré-Bendixson theorem for such perturbed systems, t…
