We study the locus of intermediate Jacobians of cubic threefolds within the moduli space $\mathcal{A}_{5}$ of complex principally polarized abelian fivefolds, and its generalization to arbitrary genus—the locus of abelian varieties with a singular odd two-torsion point on the theta divisor. Assuming that this locus has expected codimension g (which we show to be true for g≤5, and conjecturally for any g), we compute the class of this locus, and of its closure in the perfect cone toroidal… CONTINUE READING
