Abstract.

In this talk we give a variational characterization of H-convergence of sequences of non-symmetric elliptic matrices in terms of Gamma-convergence of suitably associated quadratic forms. Moreover, using purely variational arguments we also give an alternative proof of the compactness of H-convergence, originally proved by Murat and Tartar.
