摘要 运用规范化的Lyapunov-Schmidt约化方法,得到了带Neumann边界条件的Extended FisherKolmogorov系统产生超临界和次临界分歧的完整判据,给出了分歧解的具体表达式,并进一步讨论了分歧解的正则性. With normalized Lyapunov-Schmidt reduction method, a complete criterion both for supercritical and subcritical bifurca- tion of extended Fisher-Kolmogorov system with Neumann boundary condition is derived. And the exact form of bifurcated solutions is given. Moreover, the regularity of solutions is also discussed.
