where Ω is a bounded smooth domain in , , that exhibits certain symmetries and contains the origin, , , , and is a small parameter. By using the Lyapunov–Schmidt reduction method and topological degree theory, for each sufficiently large , we construct sign‐changing solutions to exhibiting k negative spikes at the vertices of a regular polygon and a single positive spike at the origin.

其中Ω是 , ,具有某些对称性并包含原点, , , 和 是一个小参数。通过使用Lyapunov–Schmidt约简方法和拓扑度理论,对于每个足够大的域,我们为 在规则多边形的顶点处显示k个负峰值,在原点处显示单个正峰值。
