An example in the gradient theory of phase transitions
ESAIM: Control, Optimisation and Calculus of Variations, Tome 7 (2002), pp. 285-289.

We prove by giving an example that when n≥3 the asymptotic behavior of functionals ∫ Ω ε|∇ 2 u| 2 +(1-|∇u| 2 ) 2 /ε is quite different with respect to the planar case. In particular we show that the one-dimensional ansatz due to Aviles and Giga in the planar case (see [2]) is no longer true in higher dimensions.
