SUMMARY:A converse of Riemann’s theorem on Jacobian varieties
DESCRIPTION:Thomas Kraemer (Humboldt-Universitaet zu Berlin)\nAula Beltrami – Giovedì 6 Giugno 2019 h.16:30\n \nAbstract. Jacobians of curves have been studied a lot since Riemann’s\ntheorem, which says that their theta divisor is a sum of copies of the\ncurve. Similarly, for intermediate Jacobians of smooth cubic threefolds\nClemens and Griffiths showed that the theta divisor is a sum of two\ncopies of the Fano surface of lines on the threefold. We prove that in\nboth cases these are the only decompositions of the theta divisor,\nextending previous results of Casalaina-Martin, Popa and Schreieder. Our\nideas apply to a much wider context and only rely on the decomposition\ntheorem for perverse sheaves and some representation theory.\n
