Summary: This article intends to give a synthetic survey about the canonical Hermitian form of a germ of a holomorphic function \(f\) with an isolated singularity at the origin in \(\mathbb C^{n+1}\). 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 [Bull. Soc. Math. Fr. 114, 385–392 (1989; Zbl 0652.32009)], is presented in the \((a,b)\)-module setting with purely local arguments.
For the entire collection see [Zbl 1119.32001].
