Witt vectors and separably closed fields with higher derivations
Submission date: 30 September 2015.
We propose a modification of the theory given by Messmer and Wood corresponding to the theory of separably closed fields. Our axioms involve Hasse-Schmidt derivations with the iterativity conditions corresponding to the Witt group.
