Equivariant Poincaré series and topology of valuations

Doc. Math., J. DMV 21, 271-286 (2016)

Summary

Summary: The equivariant with respect to a finite group action Poincaré 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 Poincaré series determines the equivariant topology of the collection of valuations.
