Title	Liftability of varieties in characteristic p
Abstract	Many “pathologies’?of varieties in characteristic p do not occur if the variety in question lifts to characteristic zero, or at least if it lifts modulo p^2. We will review classical and recent results on liftable varieties, discuss liftability of Frobenius split varieties, and present some new (quite elementary) examples of non-liftable varieties. This is joint work with Maciej Zdanowicz.
