Unit groups of group algebras of certain dihedral groups-II

In this paper, we establish the structure of [Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text] where [Formula: see text] is a finite field and [Formula: see text] is the dihedral group of order [Formula: see text]. For an odd prime [Formula: see text], we also establish the structure of [Formula: see text], when characteristic of [Formula: see text] is [Formula: see text] or [Formula: see text].
