Abstract

In an earlier paper, the authors studied a class of Allen-Cahn models for which the solution was near $1$ on a prescribed set, $T +[0, 1]^n$ where $T \subset \mathbb{Z}^n$, and near $0$ on its complement. In this note, when $T$ is finite and consists of two widely spaced subsets, $T_1$ and $l + T_2$ with $l \in \mathbb{Z}^n$, we study the asymptotic behavior of two special families of solutions as $l \to \infty$.
