    The paper establishes a relationship between finite separable extensions and norm groups of strictly quasilocal fields with Henselian discrete valuations, which yields a generally nonabelian one-dimensional local class field theory.Comment: 14 pages; revised form, to appear in manuscripta mathematica, paper [6] from the list of references has been published in the Proceedings of ICTAMI 05, Alba Iulia, Romania, 15.9-18.9. 2005; Acta Universitatis Apulensis 10/2005, 149-16

    Let EE be a primarily quasilocal field, M/EM/E a finite Galois extension and DD a central division EE-algebra of index divisible by [M ⁣:E][M\colon E]. In addition to the main result of Part I, this part of the paper shows that if the Galois group G(M/E)G(M/E) is not nilpotent, then MM does not necessarily embed in DD as an EE-subalgebra. When EE is quasilocal, we find the structure of the character group of its absolute Galois group; this enables us to prove that if EE is strictly quasilocal and almost perfect, then the divisible part of the multiplicative group Eβˆ—E ^{\ast} equals the intersection of the norm groups of finite Galois extensions of EE.Comment: 10 page
