This space is different from the moduli space of spin curves. The modular description and the boundary stra tification of the new compactification are encoded by a tropical moduli sp ace. We show that this tropical moduli space is a refinement of the moduli space of spin tropical curves. We describe explicitly the induced decompo sition of its cones. This is a joint work with Abreu and Pacini.\n\n--XX-- XX--\n\nSpeaker 2: Victor Pretti (UNICAMP)\n\nTitle: Rank 0 Asymptotic Bri dgeland stability\n\nAbstract: Bridgeland stability is a modern tool to st udy stability of objetcs in triangulated categories\, and specially in the derived category of coherent sheaves over a smooth projective variety. It s asymptotic version\, as studied by Bridgeland\, Bayer and Jardim--Macioc ia\, is known to behave like Gieseker stability for sheaves in various sit uations. In this seminar we will focus on Bridgeland stabilities over the projective space P^3 and its asymptotic behaviour for rank zero objects to prove their respective relation with Gieseker stability for sheaves.\n\nT wo 30 min presentations by PhD students or recently graduated PhDs.\n LOCATION:https://researchseminars.org/talk/BRAG/40/ END:VEVENT END:VCALENDAR
