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