1. Existência e homogeneização para um problema elíptico com fronteira livre não estacionária / Existence and homogenization for an elliptic problem with nonstationary free boundary
In this dissertation we study an elliptic problem in a bounded Lipschitz domain. Part of the boundary is moving and oscillates rapidly in the variable representing the space. Thus, we have a multi-scale free boundary problem. This problem has applications, for instance, in the construction of semiconductor films taking into account that the surface of the fi

2. Teoria de regularidade para equaÃÃes elÃpticas totalmente nÃo lineares com potenciais singulares e problemas de fronteira livre assintÃticos / Fully nonlinear singularly perturbed elliptic equations and limiting free boundary problems
In this work we develop a fully nonlinear theory for singularly perturbed elliptic equations problems with high energy activation. We esta-blish uniform and optimal gradient estimates of solutions and prove that minimal solutions are non-degenerated. For problems governed by concave equations, we establish uniform weak geometric properties of approximating l
