2.00 pm, Lecture Hall 3 Kunz's theorem Nirmal Kotal Chennai Mathematical Institute. 29-05-19 Abstract Let R be a Noetherian local ring of prime characteristic p. The Frobenious ring map R is the map r \mapsto r^p. Kunz's theorem states that R is a regular ring if and only if the Frobenious map is flat. In this talk, we will prove the theorem and then see some corollaries.
