The da Silva Machado-Seade Conjecture

da Silva Machado and Seade conjectured that weighted homogeneous isolated hypersurface singularities are exactly those admitting a logarithmic vector field transverse to the link. True: for a reduced isolated hypersurface germ in $\mathbb{C}^{n+1}$ with $n \ge 2$, or $n = 1$ and the germ irreducible, the criterion holds.
