摘要
大量文献研究均是以一次项系数为分岔参数,它们的分岔图形具有连续性,并且可以用特征值做更详细的分析,而本文以二次项系数h为分岔参数,研究了Lorenz-like系统叉形分支,并在多种情况讨论中将遇到间断的特性.
mainly study the pitch-fork bifurcation of Lorenz-like system, previous work used the coefficient of tem as bifurcation parameter and the graphes of bifurcation were continuous, and gave the detailed analysis with eigenvalue theory. This paper used the coefficient of quadratic item as bifurcation parameter and fund that bifurcation graphes are discontiuous.
