Abstract:   Let $f:(C^3,0) \longrightarrow (C,0)$ be an analytic germ. The singularity is allowed to be non-isolated. We compare the homeomorphism classes of the link of $f$, of the normalization of $f^{-1}(0)$ and of the boundary of the Milnor fibre of $f$. In the isolated case, this three manifolds are homeomorphic. In general, this is not the case in the non-isolated case.
