Rationally connected non-Fano type varieties

Algebraic Geometry 2017-12-05 v4

Abstract

Varieties of Fano type are very well behaved with respect to MMP, and they are known to be rationally connected. We study the relation between classes of rationally connected varieties and varieties of Fano type. We give examples of rationally connected varieties of dimension 3\geqslant 3 which are not birationally equivalent to Fano type varieties, thereby answering the question of Cascini and Gongyo.
