Poincare series and zeta function for an irreducible plane curve singularity

Artikel i vetenskaplig tidskrift, 2005

The Poincaré series of an irreducible plane curve singularity equals the $\zeta$-function of its monodromy, by a result of Campillo, Delgado and Gusein-Zade. This fact is derived in this paper from a formula of Ebeling and Gusein-Zade, relating the Poincaré series of a quasi-homogeneous complete intersection singularity to the Saito dual of a product of $\zeta$-functions. © 2005 London Mathematical Society.
