Let E be a field complete with respect to a discrete valuation, let F/E be a finite Galois extension of E, with Galois group G, and assume for simplicity that E and F have the same residue field. If s ≠ 1 is an element of G and if π is a prime element of F, put
$$ _{{i_G}}(s) = {v_F}(s(\pi ) - \pi ),$$
where vF denotes the valuation of F, normalized so that vF(π) = 1.
