Parametric local cohomology classes and Tjurina stratifications for \(\mu\)-constant deformations of quasi-homogeneous singularities (Q6486892)

The author illustrates by an example a method to compute the stratification by Tjurina number of the \(\mu\)-constant stratum of a quasihomogeneous function germ \(f\). It uses multiplication by \(f_t\) not on the Jacobi algebra, but on its dual, the space of local cohomology classes supported at the origin and annihilated by the partial derivatives of \(f\).NEWLINENEWLINEFor the entire collection see [Zbl 1291.32001].
