Usamos argumentos desenvolvidos por Cîrstea & Radulescu [6], Lair & Wood [20] e as técnicas empregadas são o Método de Sub e Supersolução, Teoremas de Ponto Fixo e em alguns resultados exploramos a simetria radial e algumas estimativas para equações elípticas. / In this work we studied the existence of blow-up positive solutions for the class of semilinear elliptic equations. We used arguments developed by Cîrstea & Radulescu [6], and by Lair & Shaker [20] and the techniques used are the method of Sub and Supersolution, Fixed point theorems and some results explored radial symmetry and some estimates for elliptic equations.

A principal ferramenta usada foi o Método de Sub e Supersolução, além de Regularidade Elíptica e alguns resultados de Equações Diferenciais Ordinárias. / In this dissertation, we study the existence of blow-up solution for some classes of elliptic problem, which include scalar problem and elliptic systems. The main tool used is the sub and super-solution methods combined with elliptic regularity and some results of Ordinary Differential Equations.
