A Food Chain Model with Ratio-dependent Functional Response, Impulsive Perturbations and Feedback Controls

Jian-wen Jia & Jian-feng Liu · Journal of Advances in Mathematics and Computer Science · 2012

In this paper, a food chain system with ratio-dependent functional response, impulses,feedback controls and delays is studied. By using the theorem of coincidence degree, homotopy invariance property and Lyapunov’s approach, a set of sufficient conditions for ensuring the existen...

A Delayed Monod Chemostat Competition Model with Pulsed Input and Inhibitor in Polluted Environment

Manji Sang & Jian-wen Jia · Journal of Advances in Mathematics and Computer Science · 2014

In this paper, a two microorganisms and two nutrient chemostat competitive model with time delay and impulsive effect is considered. Besides, a polluted environment and an inhibitor were considered in this model. By using the theorem of the impulsive differential equations and de...
