Weil group: Measurement, Class formation & Weil–Deligne group

In mathematics, a Weil group, introduced by André Weil, is a modification of the absolute Galois group of a local or global field, used in class field theory. For such a field F {\displaystyle F} , its Weil group is generally denoted W F {\displaystyle W_{F}} . There also exists "finite level" modifications of the Galois groups: if E / F {\displaystyle…
