Abstract

In this paper singularly perturbed vector fields X_{\varepsilon} defined in R^2 are discussed. The main results use the solutions of the linear partial diferential equation X_{\varepsilon}V = div(X_{\varepsilon})V to give conditions for the existence of limit cycles converging to a singular orbit with respect to the Hausdor distance.
