Elliptic Equations in High-Contrast Media and Applications
  In this manuscript we review some recent results about approximation of solutions of elliptic problems with high-contrast coefficients. In particular, we detail the derivation of asymptotic expansions for the solution in terms of the high-contrast of the coefficients and we consider some interesting applications. We use the Finite Element Method, which is applied in the numerical computation of terms of the asymptotic expansion. We also present an application to Multiscale Finite Elements, in particular, we numerically design approximation for the term $u_0$ with local harmonic characteristic functions. We also show the case of the linear elasticity problem, where we study the asymptotic problem with one inelastic inclusion and we provide the convergence for this expansion problem. Finally, we state some conclusions and final comments.
