Ramification groups of coverings and valuations

Takeshi Saito

Vol. 1 (2019), No. 3, 373–426
Abstract

We give a purely scheme theoretic construction of the filtration by ramification groups of the Galois group of a covering. The valuation need not be discrete but the normalizations are required to be locally of complete intersection.
