Liftings mod p2 and the Nygaard filtration

Abstract: I will revisit old results on liftings mod p2 and decompositions of de Rham complexes in positive characteristic (Deligne-I.) at the light of relations recently discovered independently by Bhargav Bhatt and myself between cotangent complexes, de Rham-Witt, and derived de Rham complexes.
