  • Cubic fourfolds with ADE singularities and K3 surfaces 
    Stegmann, Ann-Kathrin (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2020)
    In this thesis, we will give a partial classification of cubic fourfolds by their isolated ADE singularities. We have a correspondence between cubic fourfolds and complete (2,3)- intersections in ℙ^4 having both certain ...
  • 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 ...
  • Formality conjecture for K3 surfaces 
    Budur, Nero; Zhang, Ziyu (Cambridge : Cambridge Univ. Press, 2019)
    We give a proof of the formality conjecture of Kaledin and Lehn: on a complex projective K3 surface, the differential graded (DG) algebra RHom*(F; F) is formal for any sheaf F polystable with respect to an ample line bundle. ...
  • The Mori fan of the Dolgachev–Nikulin–Voisin family in genus 2 
    Hulek, Klaus; Liese, Carsten ([Erscheinungsort nicht ermittelbar] : [Verlag nicht ermittelbar], 2022)
    In this paper we study the Mori fan of the Dolgachev–Nikulin–Voisin family in degree 2 as well as the associated secondary fan. The main result is an enumeration of all maximal dimensional cones of the two fans. © by the ...
  • On the stable dynamical spectrum of complex surfaces 
    Brandhorst, Simon (Berlin ; Heidelberg : Springer, 2020)
    We characterize Salem numbers which have some power arising as dynamical degree of an automorphism on a complex (projective) 2-Torus, K3 or Enriques surface.
  • Sixfolds of generalized Kummer type and K3 surfaces 
    Floccari, Salvatore (Cambridge : Cambridge Univ. Press, 2024)
    We prove that any hyper-Kähler sixfold K of generalized Kummer type has a naturally associated manifold YK of K3[3] type. It is obtained as crepant resolution of the quotient of K by a group of symplectic involutions acting ...
  • Smoothing cones over K3 surfaces 
    Coughlan, Stephen; Sano, Taro (France : Association Epiga, 2018)
    We prove that the affine cone over a general primitively polarised K3 surface of genus g is smoothable if and only if g ≤ 10 or g = 12. We also give several examples of singularities with special behaviour, such as ...
