Title |
Kunz's theorem in ALL characteristics |
Abstract |
In the 1970s Kunz proved that a Noetherian ring of positive characteristic is regular if and only if the Frobenius is flat. I will discuss various extensions of this theorem. Then I will give a version of Kunz’s theorem in mixed characteristic (joint with Bhatt and Iyengar), and a version in characteristic zero (joint with Schwede). |
