A rationality criterion for conic bundles
V. A. Iskovskikh
Abstract:
It is that a three-dimensional variety $X$ that is a conic bundle $\pi\colon X\to S$ in the Mori sense has a base with at most double rational singularities of type $A_n$. A rationality criterion is proved subject to this assumption in the case when the discriminant curve $C\subset S$ is large enough, for example, for the case when $p_a(C)>18$.
