Existences and Numerical Simulation of Positive Solution for a Class of Unstirred Chemostat Model
摘要
Abstract
The coexistence of the steady-state solutions of an unstirred multiple food chain Chemostat model with Beddington-DeAngelis functional response is discussed. The necessary condition is given by comparison theorem of eigenvalue. By using degree theory, index of fixed point of map in cone, and spectral radius of differentiation operator theory, a sufficient condition is obtained for the existence of steady state positive solution. The coexistence is verified by numerical simulation with MATLAB software.关键词
