Title:
Old and new on the de Rham-Witt complex III. Liftings mod p2 and the Nygaard filtration I
Time & Venue:
2019.09.18 11:00-12:00 N202
Abstract:
I will discuss some open problems arising from this new approach. In the second part, I will revisit liftings mod $p^2$ and decompositions of de Rham complexes ("Deligne-Illusie") in relation with a certain filtration on the de Rham-Witt complex.
