一类分歧问题的扩充系统

The Extended Systems of a Class of Bifurcation Problems

对一类典型分歧问题进行了研究 ,构造了计算此类分歧问题的扩充系统 ,使待求的分歧点转化为扩充系统的正则点 .不但对扩充系统的正则性进行了证明 ,而且给出了扩充系统构造的一般原则 。

Study a class of typical bifurcation problem.The extended systems for computing a kind of typical bifurcation problem are constructed,not only presenting proof of regular solution but also giving general rule for the extended systems.So an efficient method for bifurcation computing is introduced.
