RESUMO

In this work we study a class of semilinear equations of the logistic type. More precisely, we consider the homogeneous and inhomogeneous cases. In the homogeneous case, we discuss the existence, nonexistence and uniqueness of positive solution as well the decay at infinity. The existence is obtained by using the method of sub-super solutions. In the inhomogeneous case, we discuss the existence of positive solution and show that the decay at infinity is not exponential. The existence is obtained by using minimizes arguments, more precisely, the Direct Method of Calculus of Variations.
