红细胞的生长是一种高阶非线性离散问题,一般方法很难确定高阶含多参数问题的Hopf分岔点。本文应用任意阶Hopf分岔代数判据对六阶红细胞存活模型的Hopf分岔点进行判定,同时利用投影法判断是否存在稳定极限环。通过分析该模型的分岔点验证了该代数判据对高阶问题的有效性以及稳定性。
The red blood cell survival model is a high-dimensional nonlinear discrete problem, the traditional criteria for Hopf bifurcation are difficult to implement. This paper applied an algebraic criterion to identify Hopf bifurcation for the six-dimensional red blood cell survival model, and analyzed stability of the generated limit circle by using projection method. Finally, it is proved that the suggested algebraic criterion is more effective and simple for high dimension problems.
