JIANG Hongling, . Existences and Numerical Simulation of Positive Solution for a Class of Unstirred Chemostat Model[J]. Acta Scientiarum Naturalium Universitatis SunYatseni, 2011,50(3):11-16.DOI:
The coexistence of the steadystate 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.
