WebarXiv:math/0407343v3 [math.AG] 17 Jan 2005 NONRATIONAL DEL PEZZO FIBRATIONS IVAN CHELTSOV Abstract. In this paper we study cubic del Pezzo fibrations f : X → P1 such that the 3-fold X is smooth and rkPic(X) = 2. These are examples of smooth 3-fold Mori fibre spaces. The 3-fold X is a divisor in the linear system 3M + nL on the rational WebApr 26, 2004 · Sextic Double Solids Ivan Cheltsov, Jihun Park We prove non-rationality and birational super-rigidity of a Q-factorial double cover X of P^3 ramified along a sextic surface with at most simple double points. We also show that the condition # Sing (X) < 15 implies Q-factoriality of X.
