Abstract

Let Σ\Sigma be a surface of constant mean curvature in R3{\mathbb R}^3 with multiple Delaunay ends. Assuming that Σ\Sigma is non degenerate in this paper we construct new solutions to the Cahn-Hilliard equation εΔu+ε1u(1u2)=ε\varepsilon\Delta u+\varepsilon^{-1}u(1-u^2)=\ell_\varepsilon in R3{\mathbb R}^3 such that as ε0\varepsilon\to 0 the zero level set of uεu_\varepsilon approaches Σ\Sigma. Moreover, on compacts of the connected components of R3Σ{\mathbb R}^3\setminus \Sigma we have 1uε01-|u_\varepsilon|\to 0 uniformly.
