Sommario:
- We fix a complex analytic normal singularity germ $(X,o)$ of dimension $\geq 2$ and a (not necessarily irreducible) reduced Weil divisor $(S,o)\subset (X,o)$. The embedded resolution of the pair determines a multi-index filtration of the local ring $\mathcal{O}_{X,o}$, which measures the embedded geometry of the pair. Furthermore, from the (induced) resolution of $(S,o)$ we also consider a multi-index filtration associated with $(S,o)$. This latter one can be lifted to a filtration of $\mathcal{O}_{X,o}$ too. The main result proves that the second filtration of $\mathcal{O}_{X,o}$ can be realized as a `limit' filtration of the first one (if we blow up certain centers sufficiently many times).
