带Neumann边界条件的Extended Fisher-Kolmogorov系统的定态分歧
Steady State Bifurcation of Extended Fisher-Kolmogorov System with Neumann Boundary Condition
【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.
【Abstract】 With normalized Lyapunov-Schmidt reduction method,a complete criterion both for supercritical and subcritical bifurcation 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.
