Resumen:
|
In this work we deal with dicritical divisors, curvettes and polynomials.These objects have been one of the main research interests of S.S. Abhyanka during his last years. In this work we provide some elementary proofs of some S.S.Abhyankar and I. Luengo results for dicriticals in the framework of forma power series. Based on these ideas we give anconstructive way to find the atypical fibres of a special pencil and give bounds for its number, which are sharper than the existing ones. Finally, we answer a question of J. Gwozdziewicz finding polynomials that reach his bound.
