This article is a sequel of the previous works [10] and [11], where we treated the Kummer, Artin-Schreier, Kummer-Artin-Schreier and Artin-Schreier-Witt theories. The unit group scheme of a group algebra plays an important role, as was pointed out by Serre in ⟨Groupes alg ebriques et corps de classes⟩.}, title = {KUMMER THEORIES FOR ALGEBRAIC TORI AND NORMAL BASIS PROBLEM}, year = {2015} }
