TITLE
Closure and commutability results for $\Gamma$-limits

ABSTRACT
Under a suitable notion of equivalence of integral densities we prove a 
$\Gamma$-closure theorem for integral functionals with standard 
$p$-growth: The limit of a sequence of $\Gamma$-convergent families is 
again a $\Gamma$-convergent family. Its $\Gamma$ limit can be recovered 
from $\Gamma$ limits of the original problems. This result not only 
provides a common basic principle for a number of linearization and 
homogenization results in elasticity theory. It also allows for new 
applications as we exemplify by proving that geometric linearization and 
homogenization of multi-well energy functionals commute. We then also 
address the case $p=1$ with its difficulties.
This is a joint work with Bernd Schmidt (Universität Augsburg).
