Entire solutions to equivariant elliptic systems with variational structure
Nicholas D. Alikakos, Giorgio Fusco
In the present paper we consider the system Δu - W_u (u) = 0, where u: R^n to R^n, for a class of potentials W: R^n to R that possess several global minima and are invariant under…

On an elliptic system with symmetric potential possessing two global minima
Nicholas D. Alikakos, Giorgio Fusco
We consider the system Δu - W_u (u) = 0, for u: R^2 -> R^2, W: R^2 -> R, where W_u (u) is a smooth potential, symmetric with respect to the u_1, u_2 axes, possessing two global min…
