Modules de Brieskorn et formes hermitiennes pour une singularité isolée d'hypersurface.
Résumé
This article intends to give a synthetic survey about the canonical hermitian form of a germ of holomorphic function $f$ with an isolated singularity at the origin in $\Bbb C ^{n+1}$. The link between this canonical hermitian form, the hermitian Poincaré duality on the Milnor ' fiber of $f$ and the variation map, proved by F. Loeser in [Lo.86] is presented in the (a,b)-module setting with purely local arguments.
