Mi, 23. Oktober 2019 Oberseminar Algebra und Geometrie

  • Dr. Giulio Bresciani (FU Berlin)
    On the (birational) section conjecture over finitely generated fields
    Zeit und Ort: 16:00-17:00 Uhr im Raum 711 (kl.), Robert-Mayerstr. 10

    We prove that, if the section conjecture holds over number fields, then it holds for every curve X over a field finitely generated over Q with a non-constant morphism to an abelian variety which is defined over a number field. Our method also gives an independent proof of the recent result by Saidi-Tyler of the fact that the birational section conjecture over number fields implies it over fields finitely generated over Q.

  • Christoph Goldner (Tübingen):
    Tropical mirror symmetry for ExP^1
    Zeit und Ort: 14:00-18:00 Uhr im Raum 711 (gr.), Robert-Mayerstr. 10

    We recall some results of tropical mirror symmetry that relate the generating series of tropical Gromov-Witten invariants of an elliptic curve E to sums of Feynman integrals. After that, we present an approach to tropical mirror symmetry in case of ExP^1. The approach is based on the floor decomposition of tropical curves which is a degeneration technique that allows us to apply the results of the elliptic curve case. The new results are joint work with Janko Böhm and Hannah Markwig.
