For this purpose, we use the variational method of critical point theory, which consists of associating the solutions of the equation to the critical points of a suitable functional. Furthermore, the nonlinearity is general and does not satisfy the well-known AmbrosettiRabinowitz condition, which makes the study of the compactness associated with the problem and the boundedness of Palais-Smale sequences more sophisticated. In this context, the main tools used to achieve our main results were the use of the mountain pass theorem and the Lions’ compactness principle, in addition to the common basis which consists of basic results of measure theory and Lebesgue integration, functional analysis and nonlinear functional analysis.Acesso AbertoEquações de Kirchhoff-SchrödingerCrescimento crítico de SobolevPotencial que decai para zero no infinitomasterThesisCNPQ::CIENCIAS EXATAS E DA TERRA::MATEMATICA
