- Title : Birationally birigid Q-Fano threefolds - Speaker : Takuzo Okada(Saga University) - Date & Time : 25 May , 2012 (Fri) 14:00~15:00 - Place : Math Science Building room 404 - Abstract : I will talk about explicit studies on the birational geometry of Q-Fano
threefold weighted complete intersections of codimension two. I will explain
which Q-Fano WCI is birationally rigid or not. For birationally non-rigid Q-Fano
WCIs, we can construct explicit links to another Mori fiber spaces. I will show
that some of them are birationally birigid, that is, there are exactly two
Q-Fano varieties in their birational classes. |
