whereε(X)|X=ζp−1 = ε, η(X)|X=ζp−1 = η, ε(X), η(X) ∈ Zp[[X]] ∗ . The important point is that one associates to the elements ε, η the seriesε(X), η(X) in order to calculate the value of the Hilbert symbol. Theorem(I. Shafarevich 1950) . Complete explicit formula for the Hilbert norm residue symbol(α, β)pn , α, β ∈ K, K ⊃ Qp(ζpn ), p 6= 2, using a special basis of the group of principal units. This formula is not very easy to use because of the special bas is of the group of units and certain difficulties with its verification for n > 1. One of applications of this formula was in the work of Yakovlev on the description of the a bsolute Galois group of a local field in terms of generators and relations. Complete formulas, which are simpler that Shafarevich’s fo rmula, were discovered in the seventies:
