چکیده
Here we focus on the geometry of P d,g, the compactification of the universal Picard variety constructed by Lucia Caporaso. In particular, we give generators and relations of its rational divisor class group, extending previous work by Alexis Kouvidakis.

On the geometry of the compactification of the universal Picard variety
Here we focus on the geometry of P d,g, the compactification of the universal Picard variety constructed by L. Caporaso. In particular, we show that the moduli space of spin curves constructed by M. Cornalba naturally injects into P d,g and we give generators and relations of the rational divisor class group of P d,g, extending previous work by A. Kouvidakis.
متن کاملThe universal $mathcal{AIR}$- compactification of a semigroup
In this paper we establish a characterization of abelian compact Hausdorff semigroups with unique idempotent and ideal retraction property. We also introduce a function algebra on a semitopological semigroup whose associated semigroup compactification is universal withrespect to these properties.
متن کاملFLOWS AND UNIVERSAL COMPACTIFICATIONS
The main purpose of this paper is to establish a relation between universality of certain P-compactifications of a semitopological semigroup and their corresponding enveloping semigroups. In particular, we show that if we take P to be the property that the enveloping semigroup of a compactification of a semitopological semigroup s is left simple, a group, or the trivial singleton semigroup, t...
متن کاملFilters and the Weakly Almost Periodic Compactification of a Semitopological Semigroup
Let $S$ be a semitopological semigroup. The $wap-$ compactification of semigroup S, is a compact semitopological semigroup with certain universal properties relative to the original semigroup, and the $Lmc-$ compactification of semigroup $S$ is a universal semigroup compactification of $S$, which are denoted by $S^{wap}$ and $S^{Lmc}$ respectively. In this paper, an internal construction of ...
متن کاملA COMPACfIFICATION OF mE UNIVERSAL PICARD VARIETY OVER mE MODULI SPACE OF STABLE CURVES
0.1. Statement of the problem. In this paper we construct a geometrically meaningful compactification for the relative degreed Picard variety associated to a family of stable curves. More precisely, let 1/ -+ B be a (proper and flat) family of stable curves of genus g and let f,,/B -+ B be the corresponding family of Jacobians; we want to answer the following question: does there exist a compac...
