    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 ...
  • Heckel, Tobias (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2020)
    To every cubic hypersurface $X$ we associate the parameter space of lines contained in $X$; this is called the Fano scheme of lines on $X$ and denoted $F(X)$. If X admits an isolated singular point of ADE-type, we prove ...
