This book develops the modern theory of upper ramification groups for local fields with imperfect residue fields, alongside classical results like the Hasse–Arf theorem. It introduces log monogenic extensions and provides new proofs of key formulas, offering essential tools for researchers in arithmetic geometry and Galois representation theory.
