The main goal of this work is to study the behavior of Discontinuous Vector Fields in a
neighborhood of a tipical singularity (tangency) using for this the regularization process
developed by Teixeira and Sotomayor [9] and, using also, some technics of the Geometric
Singular Perturbation Theory [2].
