Two-end solutions to the Allen-Cahn equation in R3\mathbb{R}^{3}

preprint2015arXivOpen access

Abstract

In this paper we consider the Allen-Cahn equation $$ -Δu = u-u^3 \ \mbox{in} \ {\mathbb R}^3 $$ We prove that for each k∈(2,+∞),k\in\left( \sqrt{2},+\infty\right), there exists a solution to the equation which has growth rate kk, i.e. ∥u−H(⋅−kln⁡r+ck)∥L∞→0 \| u-H(\cdot -k \ln r + c_k) \|_{L^\infty} \to 0 The main ingredients of our proof consist: (1) compactness of solutions with growth kk, (2) moduli space theory of analytical variety of formal dimension one.
