Corrigendum to "A Characterization of the Unit Group in Z[T x C_2]"

Abstract

We correct Lemma 3.6 and Theorem 3.7 of T.~Bilgin, O.~Kusmus, and R.~M.~Low, \emph{A Characterization of the Unit Group in $\mathbb{Z}[T\times C_2]$}, Bull.\ Korean Math.\ Soc.\ \textbf{53} (2016), no. 4, 1105-1112. In particular, the corrected statement of Theorem 3.7 is that $U_1(\mathbb{Z}[T\times C_2])\cong [F_{33}⋊F_5]⋊[T\times C_2].$
