Abstract
In this paper, which is the natural continuation and generalization of Fesenko's non-abelian reciprocity map, we extend the theory of Fesenko to infinite -Galois extensions over a local field , with finite residue-class field of elements, satisfying and where the residue-class degree . More precisely, for such extensions , fixing a Lubin-Tate splitting over , we construct a 1-cocycle, \pmb{\Phi}_{L/K}^{(\phi)}:\text{Gal}(L/K)\to K^\times/N_{L_0/K}L_0^\times\times U_{\widetilde{\mathbb X}(L/K)}^\diamond /Y_{L/L_0}, where , and study its functorial and ramification-theoretic properties. The case recovers the theory of Fesenko.
