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.
