EUDML Hilbert-symbol equivalence of global function fields

The Hilbert symbol was introduced by David Hilbert (1897, sections 64, 131, 1998, English translation) in his Zahlbericht, with the slight difference that he defined it for elements of global fields rather than for the larger local fields. The Hilbert symbol has been generalized to higher local fields. See more In mathematics, the Hilbert symbol or norm-residue symbol is a function (–, –) from K × K to the group of nth roots of unity in a local field K such as the fields of reals or p-adic numbers .
