On completion of unimodular rows over polynomial extension of finitely generated rings over $\mathbb{Z}$
Published 6 May 2020 in math.AC | (2005.03485v2)
Abstract: In this article, we prove that if $R$ is a finitely generated ring over $\mathbb{Z}$ of dimension $d, d\geq2, \frac{1}{d!}\in R$, then any unimodular row over $R[X]$ of length $d+1$ can be mapped to a factorial row by elementary transformations.
