RESUMO

In this dissertation we get resulted of multiplicity of not trivial weak solutions for the problem -Du + V (x)u = f (x; u); x 2 RN; where V is continuous, f is C1, with f (x; 0) = 0 and f is asymptotically linear. We use variationals methods and the theory of critical groups, to get and to distinguish the solutions. We also present results of existence of not trivial solution for the problem -Du + V (x)u = f (u); x 2 RN; where V and f are continuous functions. We use the techniques of concentration of compactness and approximation of the domain for bounded subsets, to get the solution
