| چکیده | ||
| Let $\mathbb{F}_{q}D_{2n}$ be the group algebra of $D_{2n}$, the dihedral group of order $2n$, over $\mathbb{F}_{q}=GF(q)$. In this paper, we establish the structure of $\mathcal{U}(\mathbb{F}_{2^{k}}D_{2n})$, the unit group of $\mathbb{F}_{2^{k}}D_{2n}$ and that of its normalized unitary subgroup $V_{*}(\mathbb{F}_{2^{k}}D_{2n})$ with respect to canonical involution $*$ when $n$ is odd. | ||
