Abstract:

This article is devoted to obtain the $\Gamma$-limit, as $\epsilon$ tends to zero, of the family of functionals $$F{\epsilon}(u)=\int{\Omega}f\Bigl(x,\frac{x}{\epsilon},..., \frac{x}{\epsilonn},\nabla u(x)\Bigr)dx\,,$$ where $f=f(x,y^1,...,y^n,z)$ is periodic in $y^1,...,y^n$, convex in $z$ and satisfies a very weak regularity assumption with respect to $x,y^1,...,y^n$. We approach the problem using the multiscale Young measures.

Keywords: Young Measures, Gamma-convergence, discontinuous integrands, iterated homogenization, multiscale convergence
