  • Elliptic K3 surfaces and their moduli: dynamics, geometry and arithmetic 
    Mezzedimi, Giacomo (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2021)
    This thesis deals with K3 surfaces and their moduli spaces. In the first part we identify a class of complex K3 surfaces, called of zero entropy, with a particularly simple (but infinite) automorphism group, naturally ...
  • Failures of weak approximation in families 
    Bright, M.J.; Browning, T.D.; Loughran, D. (Cambridge : Cambridge University Press, 2016)
    Given a family of varieties over a number field, we determine conditions under which there is a Brauer-Manin obstruction to weak approximation for 100% of the fibres which are everywhere locally soluble. © The Authors 2016.
  • Specialization of Mordell–Weil ranks of abelian schemes over surfaces to curves 
    Keller, Timo (Singapore [u.a.] : World Scientific, 2023-03-27)
    Using the Shioda–Tate theorem and an adaptation of Silverman’s specialization theorem, we reduce the specialization of Mordell–Weil ranks for abelian varieties over fields finitely generated over infinite finitely generated ...
  • Torsors and generalized Cox rings for Manin's conjecture 
    Pieropan, Marta (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2015)
