Quasi-Frobenius-splitting and lifting of Calabi-Yau varieties in characteristic $p$
Published 19 Apr 2017 in math.AG | (1704.05604v2)
Abstract: Extending the notion of Frobenius-splitting, we prove that every finite height Calabi-Yau variety defined over an algebraically closed field of positive characteristic can be lifted to the ring of Witt vectors of length two.
