Abstract

Let EE be a field satisfying the following conditions: (i) the pp-component of the Brauer group Br(E)(E) is nontrivial whenever pp is a prime number for which EE is properly included in its maximal pp-extension; (ii) the relative Brauer group Br(L/E)(L/E) equals the maximal subgroup of Br(E)(E) of exponent pp, for every cyclic extension L/EL/E of degree pp. The paper proves that finite abelian extensions of EE are uniquely determined by their norm groups and related essentially as in the classical local class field theory. This includes analogues to the fundamental correspondence, the local reciprocity law and the local Hasse symbol.
