Equivariant Poincar\'e series and topology of valuations

Abstract

The equivariant with respect to a finite group action Poincar\'e series of a collection of $r$ valuations was defined earlier as a power series in $r$ variables with the coefficients from a modification of the Burnside ring of the group. Here we show that (modulo simple exceptions) the equivariant Poincar\'e series determines the equivariant topology of the collection of valuations.
