Ramification group: Ramification theory of valuations, Ramification groups in lower numbering & Ramification groups in upper numbering

In number theory, more specifically in local class field theory, the ramification groups are a filtration of the Galois group of a local field extension, which gives detailed information on the ramification phenomena of the extension.
