摘要:

证明了若$\mathbb{F}$是一个零特征的代数闭域,且在$\mathbb{Q}$上具有无限超越度,则存在${\rm SL}_n(\mathbb{F})$和${\rm GL}_n(\mathbb{F})$的域自同构$φ$,使得$R(φ)=1$ .这一事实意味着${\rm SL}_n(\mathbb{F})$和${\rm GL}_n(\mathbb{F})$不具有$R_{\infty}$ -性质。然而,如果$\mathbb{F}$在$\mathbb{Q}$上的超越度是有限的,则已知${\rm SL}_n(\mathbb{F})$和${\rm GL}_n(\mathbb{F})$具有$R_{\infty}$ -性质。

英文摘要:

We prove that if $\mathbb{F}$ is an algebraically closed field of zero characteristic which has infinite transcendence degree over $\mathbb{Q}$, then there exists a field automorphism $φ$ of ${\rm SL}_n(\mathbb{F})$ and ${\rm GL}_n(\mathbb{F})$ such that $R(φ)=1$. This fact implies that ${\rm SL}_n(\mathbb{F})$ and ${\rm GL}_n(\mathbb{F})$ do not possess the $R_{\infty}$-property. However, if the transcendece degree of $\mathbb{F}$ over $\mathbb{Q}$ is finite, then ${\rm SL}_n(\mathbb{F})$ and ${\rm GL}_n(\mathbb{F})$ are known to possess the $R_{\infty}$-property.
