Stationary layered solutions for a system of Allen-Cahn type equations

We consider a class of semilinear elliptic system of the form −∆u(x,y)+∇W(u(x,y))=0, (x,y)∈R2, where W : R2 → R is a double well non negative symmetric potential. We show, via variational methods, that if the set of solutions to the one dimensional system −q ̈(x) + ∇W(q(x)) = 0, x ∈ R, which connect the two minima of W as x → ±∞ has a discrete structure, then the system has infinitely many layered solutions
