Multiscale Homogenization of Convex Functionals with Discontinuous Integrand

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