 Old and new on the de Rham-Witt complex III. Liftings mod p2 and the Nygaard filtration I

  2019.09.18(星期三),11:00-12:00

  点:数学院南楼N202

 要: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.
