Abstract
In this paper we provide some results pertaining to asymptotic behaviour as $\varepsilon\str 0$ of the finite-energy sequences of the one-dimensional Cahn-Hilliard functional
\(I^{\varepsilon}_0(u)=\int_{0}^{1}\Big({\varepsilon}^2u'^2(s)+W(u(s))\Big)ds,\)
where \(u\in {\rm H}^{1}\oi{0}{1}\) and where W is a multi-well potential endowed with a non-standard integrability condition. We introduce a new class of finite-energy sequences, we recover its underlying geometric properties as \(\vrepsilon\str 0\), and obtain the related a priori estimates.
