On some families of Gushel-Mukai fourfolds
arXiv:2002.07026
Abstract
We give explicit descriptions of some Noether-Lefschetz divisors in the moduli space of Gushel-Mukai fourfolds. As a consequence we obtain that their Kodaira dimension is negative.
arXiv commentA remark of Debarre and Kuznetsov that extends the validity of the main result has been added (see Cor. 2.5). This version will appear in Algebra & Number Theory
