Characterization of $V(\mathbb{Z}C^+_n )$ of rank $\le 4$
Abstract
There are only a few cases for cyclic groups $C_n$; where the
unit group of their integral group rings are determined. In this article, we
have completed the characterization of torsion-free part $U_1(\mathbb{Z}C_n^{+}
)$ of the
integral group ring of cyclic group $C_n$, for $n=11, 15, 16, 20, 24$ and $30$ where $\rho\leq 4$. We explicitly find all the generators.
