Abstract:We consider a class of semilinear elliptic equations of the form
$$label{eq:abs} -Delta u(x,y)+a(x)W'(u(x,y))=0,quad (x,y)inmathbb{R}^{2}$$
where $${a:mathbb{R}tomathbb{R}}$$ is a periodic, positive function and $${W:mathbb{R}tomathbb{R}}$$ is modeled on the classical two well Ginzburg-Landau potential $${W(s)=(s^{2}-1)^{2}}$$ . We show, via variational methods, that if the set of solutions to the one dimensional heteroclinic problem
$$-ddot q(x)+a(x)W'(q(x))=0,quad xinmathbb{R},quad q(pminfty)=pm 1,$$
has a discrete structure, then (0.1) has infinitely many solutions periodic in the variable y and verifying the asymptotic conditions $${u(x,y)topm 1}$$ as $${xtopminfty}$$ uniformly with respect to $${yinmathbb{R}}$$ .
