Abstract:
In this paper, existence theorems are established for Neumann problems for semilinear elliptic equations at resonance together with Landesman-Lazer condition revisited. Our existence results follow as an application of the Saddle point Theorem together with a standard eigenspace decomposition.

O objetivo deste trabalho é estudar a existência, multiplicidade e não existência de soluções para problemas elípticos não-lineares dependendo de um parâmetro sob uma hipótese do tipo Landesman-Lazer. Para estabelecer a existência de solução combinamos o Método de Redução de Lyapunov-Schmidt e a técnica de congelamento do termo gradiente com argumentos de truncamento e aproximação através de métodos de bootstrap. Não há restrição de crescimento no infinito sobre o termo não-linear o qual pode mudar de sinal.
The purpose of this work is to study existence, multiplicity and non existence of solutions for nonlinear elliptic problems depending on a parameter under Landesman-Lazer type hypotheses. In ordem to establish the existence of solution we combine the Lyapunov-Schmidt Reduction Method and the term gradient freeze technique with truncation and approximation arguments via bootstrap methods. There is no growth restriction at infinity on the nonlinear term and it may change sign.

Abstract:
The monograph is devoted to the study of nonlinear first order systems in the plane where the principal term is the gradient of a positive and positively 2-homogeneous Hamiltonian (or the convex combination of two of such gradients). After some preliminaries about positively 2-homogeneous autonomous systems, some results of existence and multiplicity of T-periodic solutions are presented in case of bounded or sublinear nonlinear perturbations. Our attention is mainly focused on the occurrence of resonance phenomena, and the corresponding results rely essentially on conditions of Landesman-Lazer or Ahmad-Lazer-Paul type. The techniques used are predominantly topological, exploiting the theory of coincidence degree and the use of the Poincaré-Birkhoff fixed point theorem. At the end, other boundary conditions, including the Sturm-Liouville ones, are taken into account, giving the corresponding existence and multiplicity results in a nonresonant situation via the shooting method and topological arguments.

Abstract:
This thesis is devoted to the study of several problems arising in the field of nonlinear analysis. The work is divided in two parts: the first one concerns existence of oscillating solutions, in a suitable sense, for some nonlinear ODEs and PDEs, while the second one regards the study of qualitative properties, such as monotonicity and symmetry, for solutions to some elliptic problems in unbounded domains. Although the topics faced in this work can appear far away one from the other, the techniques employed in different chapters share several common features. In the firts part, the variational structure of the considered problems plays an essential role, and in particular we obtain existence of oscillating solutions by means of non-standard versions of the Nehari's method and of the Seifert's broken geodesics argument. In the second part, classical tools of geometric analysis, such as the moving planes method and the application of Liouville-type theorems, are used to prove 1-dimensional symmetry of solutions in different situations.
