T-coercivity for the homogenization of sign-changing coefficients scalar problems with extreme contrasts

Abstract : We study the homogenization of a diffusion-type problem, for sign-changing conductivities with extreme contrasts. The weak limit, which is proved to be the same as in the elliptic case of positive conductivities, has an explicit dependence on the conductivities.
