The purpose of this paper is to extend the notions of generalised Poincaré series and divisorial generalised Poincaré series (of motivic nature) introduced by Campillo, Delgado and Gusein-Zade for complex curve singularities to curves defined over perfect fields, as well as to express them in terms of an embedded resolution of curves.
This paper deals with the study of the behaviour of the value semigroup of a curve singularity define over a global field reduced modulo a maximal ideal. We also define a global zeta function of the curve by means of motivic integration over a suitable ring of adéles, whose reduction modulo a maximal ideal will coincide with some already known zeta functions of the singularity.
Let $O$ be a one-dimensional Cohen-Macaulay local ring having a finite field as a coefficient field. The aim of this work is to extend the explicit computations of the Stöhr Zeta Function of $O$ for one and two branches to an arbitrary number of them, obtaining in this general case an upper bound for the coefficients of the zeta function, instead of an equality. The calculations are based on the use of the value semigroup of a curve singularity and a suitable classification of the maximal points of the semigroup.
Let $b$ be a fractional ideal of a one-dimensional Cohen-Macaulay local ring $O$ containing a perfect field $k$. This paper is devoted to the study some $O$-modules associated with $b$. In addition, different motivic Poincaré series are introduced by considering ideal filtrations associated with $b$; the corresponding functional equations of these Poincaré series are also described.
