Hilbert function, generalized Poincar, series and topology of plane valuations

To a multi-index filtration (say, on the ring of germs of functions on a germ of a complex analytic variety) one associates several invariants: the Hilbert function, the Poincar, series, the generalized Poincar, series, and the generalized semigroup Poincar, series. The Hilbert function and the generalized Poincar, series are equivalent in the sense that each of them determines the other one. We show that for a filtration on the ring of germs of holomorphic functions in two variables defined by a collection of plane valuations both of them are equivalent to the generalized semigroup Poincar, series and determine the topology of the collection of valuations, i.e. the topology of its minimal resolution.
