| Apr 4 at 17:39 | comment | added | kvicente | Yeah, I guess my flawed understanding of this caused a no so clear question. I mean removing the 3 holomorphic spheres in the anticanonical divisor (I referred to each one of those spheres as an exceptional sphere). | |
| Apr 4 at 17:31 | comment | added | YHBKJ | I don't understand the question, the symplectic form has no chance of being exact if you only remove the exceptional divisor. There are holomorphic spheres in the anticanonical divisor. | |
