S¹ attractor bifurcation analysis for a three-species cooperating model

Blow-up in a three-species cooperating model

The properties of solutions for a parabolic system with homogeneous Dirichlet boundary conditions, which arises in a cooperating three-species food chain model, are investigated. ‘It is shown that global solutions exist if the intraspecific competitions are strong whereas blowup solutions exist under certain conditions if the intra-specific competitions are weak. @ 2004 Elsevier Ltd.

BIFURCATION ANALYSIS OF A DDE MODEL OF THE CORAL REEF

‎In this paper‎, ‎first we discuss a local stability analysis of model was introduced by P‎. ‎J‎. ‎Mumby et‎. ‎al‎. ‎(2007)‎, ‎with $frac{gM^{2}}{M+T}$ as the functional response term‎. ‎We conclude that the grazing intensity is the important parameter to control the existence or extinction of the coral reef‎. ‎Next‎, ‎we consider this model under the influence of the time delay as the bifurcat...

A three-scroll chaotic attractor

This Letter introduces a new chaotic member to the three-dimensional smooth autonomous quadratic system family, which derived from the classical Lorenz system but exhibits a three-scroll chaotic attractor. Interestingly, the two other scrolls are symmetry related with respect to the z-axis as for the Lorenz attractor, but the third scroll of this three-scroll chaotic attractor is around the z-a...
