1. Soluções tipo blow-up para equações elípticas quasilineares com termo semilinear satisfazendo a condição de Keller-Osserman
Neste trabalho estudamos existência de soluções C1 (no sentido das distribuições) para problemas do tipo {∆pu=F(x,u)+λV (x,y)|∇u|σ em Ω,} u≥ 0 em Ω; u (x) x→∂Ω → ∞, onde Ω ⊂RN é um domínio (possivelmente não limitado), 1

3. ABP estimates and Ambrosetti-Prodi type problems for nonlinear differential operators / Estimativas ABP e problemas do tipo Ambrosetti-Prodi para operadores diferenciais não lineares
The aim of this work is to obtain ABP estimates for fully nonlinear operators and to study problems of the Ambrosetti-Prodi type for the p-Laplacian operator in two cases: superlinear case for the equation and the sublinear case for the system. For this, we use the sub and supersolution method and the Leray Schauder degree theory, to obtain in the two cases,

4. Inexistencia de blow-up hiperbolico simples para a equação quasi-geostrofica
Nonexistence of simple hyperbolic blow-up for the quasigeostrophic equation. This master dissertation deals with the quasigeostrophic equations, a system of integro-differential equations that has been proposed as a model for the process of large-scale front formation in the atmosphere. These equations have a structure that resembles the system of two dimens

6. Blow-up of solutions of nonlinear wave equations in three space dimensions
Solutions u(x, t) of the inequality □u ≥ A|u|p for x ε R3, t ≥ 0 are considered, where □ is the d'Alembertian, and A,p are constants with A > 0, 1 < p < 1 + √2. It is shown that the support of u is compact and contained in the cone 0 ≤ t ≤ t0 -|x - x0|, if the “initial data” u(x, 0), ut(x, 0) have their support in the ball|x - x0| ≤ t0.
