E, as soluções são pontos críticos do funcional energia associado ao problema. Para alcançar nossos objetivos, será fundamental o estudo das variedades de Ruiz e de Nehari, o Princípio Variacional de Ekeland, o teorema do Passo da Montanha, e o lema Concentração de Compacidade. / In this work we are interested in studying the results of existence and nonexistence of solution, behavior of the energy functional and Palais-Smale condition for systems of equations of the type Schrödinger-Poisson; by using variational approach. In fact the solutions are critical points of the energy functional associated with the problem. To achieve our goals, it is essential to study the Manifolds of Ruiz and Nehari, the Ekeland Variational Principle, the Mountain Pass theorem, and the Concentration-Compactness argument.

For this, we will use the Ekeland s Variational Principle and the Mountain Pass Theorem without the Palais-Smale condition in combination with a version of the Trudinger-Moser inequality. / Teorema do Passo da Montanha, Principio variacional de Ekeland, equação de Schrodinger, Desigualdade de Trudinger-Moser, Crescimento Exponencial.
