| Dec 13, 2012 at 7:42 | comment | added | rita | Thank you, Sándor. You are completely right: 1) I did not know the Miyaoka-Mori criterion, and 2) actually I am looking for an elementary proof, specific to the situation. The MM criterion says Fano varieties are uniruled. How does one show that they are actually unirational? | |
