I knew it should correspond to holomorphic symplectic manifolds (perhaps "irreducible"?) and there is a whole $\mathbb{P}^1$ of such complex structures.. But what I was looking for in my answer was a bit more "à la Grothendieck": i.e. some spaces "over $\mathbb{H}$" in some suitable sense. (holom sympl manif's are definitely "over $\mathbb{C}$") | |
