| Sep 28, 2012 at 0:44 | comment | added | Mohan | Any complete intersection surface in projective space has $q=0$, so it can not be an Abelian surface. | |
| Sep 28, 2012 at 0:33 | comment | added | Johnson-Leung | This is explicit: The Weil restriction of an elliptic curve over a quadratic extension is an abelian surface. Restriction of scalars of the ideal of the curve gives two equations in four variables. I'm not an algebraic geometer, but I think that makes it a complete intersection. | |
