| May 17, 2020 at 2:38 | comment | added | Anthony Conway | @R.vanDobbendeBruyn : no sensible reason, other than it is a vice of my trade, knot theorists often work with $\mathbb{Z}[t^{\pm 1}]$ instead of $\mathbb{Z}[t]$. | |

| May 16, 2020 at 22:54 | comment | added | YCor | @R.vanDobbendeBruyn since there's a single question in the post, I'm not sure what you mean by "the stronger question". Do you mean, for every $S$ instead of this specific one? | |

| May 16, 2020 at 22:24 | comment | added | R. van Dobben de Bruyn | Out of curiosity: is there a reason you don't ask the stronger question about $\mathbf Z[t]$? That would be an even closer analogue to Quillen–Suslin. | |
