DESCRIPTION:Title: <a href="https://researchseminars.org/talk/TGiZ/17/">A 
 universal tropical Jacobian over the moduli space of tropical curves</a>\n
 by Marco Pacini (Universidade Federal Fluminense) as part of Tropical Geom
 etry in Frankfurt/Zoom TGiF/Z\n\n\nAbstract\nWe introduce polystable divis
 ors on a tropical curve\, which are the tropical analogue of polystable to
 rsion-free rank-1 sheaves on a nodal curve. We show how to construct a uni
 versal tropical Jacobian by means of polystable divisors on tropical curve
 s. This space can be seen as a tropical counterpart of Caporaso universal 
 Picard scheme. This is a joint work with Abreu\, Andria\, and Taboada.\n
