| Sep 24 at 8:52 | comment | added | Balazs | There is "Moduli spaces M_{g,n}(W) for surfaces" by Valery Alexeev arxiv.org/pdf/alg-geom/9410003, which constructs a relevant moduli space. Perhaps forward searching for papers referring to this one will turn up something useful. | |
| Sep 24 at 8:06 | comment | added | Jason Starr | Certainly there are cycle classes on moduli spaces of rational curves “counting” such surfaces. However, these are not (typically) symplectic invariants, nor do they have the other good properties of Groningen-Witten invariants. You can sometimes use Gromov-Witten invariants to deduce existence of rational surfaces (and this is a symplectic invariant). | |
