Hodge structure on the singular cohomology of singular cubic fourfolds
Algebraic Geometry Seminar
Speaker Hyunsuk Kim University of Michigan Considering the singular cohomology of a cubic fourfold yields a morphism from the moduli space of (smooth) cubic fourfolds to the period domain. Both spaces have natural compactifications, the GIT moduli space of cubic fourfolds parametrizing all GIT polystable objects, and the Baily-Borel compactification of the period …
