Abstract:

The homogenization of Dirichlet minimum problems is studied for integral functionals of the type $$u\in u{0,h}+W{1,\infty}0\mapsto\int\Omega f(hx,\nabla u)dx,$$ where $\Omega$ is a smooth bounded open set, $\{u_{0,h}\}$ is a converging sequence in $L^1(\Omega)$, and when the admissible functions are subject to a constraint of the type $$u\hbox{ is constant in }\Omega\cap{1\over h}S\hbox{ for every }S\in{\cal C},$$ where $\cal C$ is a $]0,1[^n$-periodic collection of subsets of $*R*^n$, and the constant value of $u$ is not fixed a priori.

An homogenization formula is proved, and the homogenization process is proved in both the settings of Sobolev and $BV$ spaces.

Some examples are also discussed.
