Resumen de An elementary proof of the invariance and inversion of characteristic pairs

C. Ana Núñez

• The purpose of this paper is to give a short and elementary proof of the invariance and the inversion of the characteristic pairs of an irreducible plane algebroid curve, using the concept of saturation given by Campillo in [2]. The inversion and invariance of these pairs is proved by Abhyankar in [1] using direct computations.
