متن کاملFamilies of Rationally Connected Varieties
1.1. Statement of results. We will work throughout over the complex numbers, so that the results here apply over any algebraically closed field of characteristic 0. Recall that a proper variety X is said to be rationally connected if two general points p, q ∈ X are contained in the image of a map g : P → X . This is clearly a birationally invariant property. When X is smooth, this turns out to ...
