Abstract

In the present paper, ramification invariants of complete discrete valuation fields of prime characteristic p with imperfect residue field are studied. Using Witt vectors, ramification breaks of cyclic extensions of degree p2 of such a field are calculated. Necessary and sufficient conditions for a pair of natural numbers to be ramification breaks of a cyclic extension of degree p2 are obtained.
