Sažetak

In this paper we extend the consideration of G. Leoni
pertaining to the finite-energy sequences of the one-dimensional
Cahn-Hilliard functional
\[
I^{\varepsilon}_0(u)=\int_{0}^{1}\Big({\varepsilon}^2
u'^2(s)+W(u(s))\Big)ds,
\]
where \(u\in {\rm H}^{1}(0,1)\) and where \(W\) is a two-well
potential with symmetrically placed wells endowed with a
non-standard integrability condition. We introduce several new
classes of finite-energy sequences, we recover their underlying geometric properties as
\(\varepsilon\longrightarrow 0\), and we prove the related compactness result.
