Stable solutions of the Allen-Cahn equation in dimension 8 and minimal cones. (English) Zbl 1281.35046
In this paper, the construction of entire solutions of the Allen-Cahn equation $\Delta u+u - u^{3}=0 \quad \text{in} \;\mathbb{R}^{n+1}$ is considered, where $$n \geq 1$$. The existence of bounded stable solutions, whose zero sets are not hyperplanes, is shown for $$n+1\geq 8$$.
