Abstract:

We prove by giving an example that when $n> 2$ the asymptotic behavior of functionals

intOmega eps
\nabla2 u
2 + (1-
\nabla u
2)2eps

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 is no longer true in higher dimensions.
