The Hensel-Shafarevich canonical basis in complete discrete valuation fields

Journal of Mathematical Sciences Aims and scope Submit manuscript

Starting from Hensel’s generating set of principal units, we construct a basis of the module of principal units in the multiplicative group of a complete discrete valuation field with a residue field of prime characteristics. The uniqueness of the above basis is proved, as well as the uniqueness of the canonical Shafarevich basis.
