研究了区间上非局部Allen-Cahn方程的Neumann问题。主要结果是在奇对称解的分岔曲线上发现了对称破缺(二次)分岔点。我们的证明是基于相关的积分映射的水平集分析。利用完全椭圆积分的方法证明了二次分歧点的唯一性。我们还展示了一些关于全局分岔结构的数值模拟。
This paper studies the Neumann problem of a nonlocal Allen–Cahn equation in an interval. A main result finds a symmetry breaking (secondary) bifurcation point on the bifurcation curve of solutions with odd-symmetry. Our proof is based on a level set analysis for the associated integral map. A method using the complete elliptic integrals proves the uniqueness of secondary bifurcation point. We also show some numerical simulations concerning the global bifurcation structure.
