Kristian Ranestad (UiO): Kummer surfaces and hyperkähler fourfolds, as degeneracy loci
Kristian Ranestad (UiO), gives the Seminar in Algebra and Algebraic Geometry:
"Kummer surfaces and hyperkähler fourfolds, as degeneracy loci"
Abstract: Kummer quartic surfaces may be constructed as both symmetric and Lagrangian degeneracy loci.
I shall discuss these constructions, relations between them, and similar constructions of hyperkähler fourfolds, in a report on common work with Atanas Iliev, Grzegorz and Michal Kapustka.
