高阶格是一阶性质吗?

Is being a higher rank lattice a first order property?

Nir Avni, Chen Meiri

摘要:

证明了在群的一阶语言中存在一个句子$φ$,使得有限生成群$Γ$满足$φ$当且仅当$Γ$同构于一个$\mathrm{PSL}_n(O)$形式的群,其中$n \geq 3$和$O$是数域中的$S$ -整数环.

英文摘要:

We show that there is a sentence $φ$ in the first order language of groups such that a finitely generated group $Γ$ satisfies $φ$ if and only if $Γ$ is isomorphic to a group of the form $\mathrm{PSL}_n(O)$, where $n \geq 3$ and $O$ is a ring of $S$-integers in a number field.
