摘要翻译:
本文研究了当$R$为UFD时,$R[X,y]$的三长多项式自同构的结构。利用这些结果证明了如果$\text{SL}_m(R[X_1,X_2,...,X_n])=\text{E}_m(R[X_1,X_2,...,X_n])$对于所有$n,\ge0$和对于所有$m\ge3$,则$r[X,y]$的所有长度三个多项式自同构是稳定的。

英文摘要:
We study the structure of length three polynomial automorphisms of $R[X,Y]$ when $R$ is a UFD. These results are used to prove that if $\text{SL}_m(R[X_1,X_2,..., X_n]) = \text{E}_m(R[X_1,X_2,..., X_n])$ for all $n,\ge 0$ and for all $m \ge 3$ then all length three polynomial automorphisms of $R[X,Y]$ are stably tame.
