Abstract

Earlier, for an action of a finite group GG on a germ of an analytic variety, an equivariant GG-Poincar\'e series of a multi-index filtration in the ring of germs of functions on the variety was defined as an element of the Grothendieck ring of GG-sets with an additional structure. We discuss to which extend the GG-Poincar\'e series of a filtration defined by a set of curve or divisorial valuations on the ring of germs of analytic functions in two variables determines the (equivariant) topology of the curve or of the set of divisors.
