New rational cubic fourfolds arising from Cremona transformations


It is conjectured that two cubic fourfolds are birational if their associated K3 categories are equivalent. We prove this conjecture for very general cubic fourfolds containing a Veronese surface, where the birational maps are induced from a Cremona transformation. Using these birational maps, we find new rational cubic fourfolds. This is joint work with Yu-Wei Fan.
