The purpose of this work is to study the ambient bordism of sub-manifolds of a given differentiable manifold. More specifically let us consider the following problem: "Let Nⁿ be a manifold and K^K ⊂ N a compact and oriented sub-manifold. Is there a sub-manifold W^k+1 ⊂ N, compact, oriented, with boundary, whose boundary is K?". In chapter 2 is formuled a necessary condition for the existence of W. This condition includes concepts of Algebraic Topology and says that if W exists, then K is homologous to zero in M. But sometimes this conditionis not sufficient for the existence of the bordism, according to some examples showed in this same chapter. The principal result of this work is in chapter 5 and affirms that if n = 3, K =1 and M is compact and oriented, then the condition above is also sufficient to the existence of W.
