Fundamental group of discriminant complements of Brieskorn–Pham polynomials
[Groupe fondamental du complément de la discriminante des singularités de Brieskorn–Pham]
Comptes Rendus. Mathématique, Volume 345 (2007) no. 2, pp. 93-96.

En cette Note nous rapellons la monodromie de tresses pour le discriminants de singularités d'une hypersurface et nous présentons deux résultats de Lönne (2003) : la monodromie de tresses associée aux singularités de Brieskorn–Pham est donnée par un nombre fini de tresses, et nous en déduisons une très belle présentation finie du groupe fondamental d'un complément d'une discriminante.

In this Note we recall the braid monodromy of discriminants of hypersurface singularities and present two results from Lönne (2003): the braid monodromy associated to hypersurface singularities of Brieskorn–Pham type is given explicitly in terms of finitely many braids, and we show how this leads to very nice finite presentations of fundamental groups of the discriminant complements.
