1. G-convergence and homogenization of sequences of linear and nonlinear partial differential operators
Abstract : In this thesis we study G-convergence for sequences of linear and nonlinear elliptic and parabolic problems. We also study the special case of homogenization for such problems. READ MORE

3. G-Convergence and Homogenization of some Sequences of Monotone Differential Operators
Abstract : This thesis mainly deals with questions concerning the convergence of some sequences of elliptic and parabolic linear and non-linear operators by means of G-convergence and homogenization. In particular, we study operators with oscillations in several spatial and temporal scales. READ MORE

4. Multi-scale methods for wave propagation in heterogeneous media
Abstract : Multi-scale wave propagation problems are computationally costly to solve by traditional techniques because the smallest scales must be represented over a domain determined by the largest scales of the problem. We have developed new numerical methods for multi-scale wave propagation in the framework of heterogeneous multi-scale methods. READ MORE

5. G-Convergence and Homogenization of some Monotone Operators
Abstract : In this thesis we investigate some partial differential equations with respect to G-convergence and homogenization. We study a few monotone parabolic equations that contain periodic oscillations on several scales, and also some linear elliptic and parabolic problems where there are no periodicity assumptions.
