Liftings mod p^{2} and the Nygaard filtration

__Abstract__: I will revisit old results on liftings mod p^{2} 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.
