Explain the proof that very general cubic fourfolds are irrational.
Algebraic Geometry Seminar: Intersection theory of Noether-Lefschetz cycles on A_g
Aitor Iribar Lopez (ETH Zurich)
Abelian varieties with elliptic subgroups provide cycles on the moduli space of principally polarized abelian varieties. Even though the...
