A variety that cannot be dominated by one that lifts
In the sixties, Serre constructed a smooth projective variety in characteristic p that cannot be lifted to characteristic 0. If a variety doesn't lift, a natural question is whether some variety related to it does lift. We construct an example of a smooth projective variety that cannot be rationally dominated by a smooth projective variety that lifts.
