具有可变产量的恒化器的全局动力学

Global dynamics of the chemostat with variable yields

Tewfik Sari

摘要:

本文考虑了一类具有单调和非单调响应函数、不同去除率和可变产量的恒化器中$n$种群间的竞争模型.我们表明,只有最低的盈亏平衡浓度的物种生存,提供了额外的技术条件的增长功能和产量得到满足。LaSalle推广定理是李雅普诺夫稳定性理论的主要工具。

英文摘要:

In this paper, we consider a competition model between $n$ species in a chemostat including both monotone and non-monotone response functions, distinct removal rates and variable yields. We show that only the species with the lowest break-even concentration survives, provided that additional technical conditions on the growth functions and yields are satisfied. LaSalle's extension theorem of the Lyapunov stability theory is the main tool.
