论文摘要
The well-known theorem of Shalom--Vaserstein and Ershov--Jaikin-Zapirain states that the group $\mathrm{EL}_n(\mathcal{R})$, generated by elementary matrices over a finitely generated commutative ring $\mathcal{R}$, has Kazhdan's property (T) as soon as $n\geq3$.如果戒指$ \ mathcal {r} $被通勤的RNG(戒指但没有身份)代替,这是不再正确的,因为nilpotent的商$ \ mathrm {el} _n(\ MathCal {r}/\ Mathcal {r}/\ Mathcal {r}^k)$。在本文中,我们证明,即使在这种情况下,只要$ n $就足够大,就可以满足一个可以替换属性(t)的特定属性(t)$ \ mathrm {el} _n(\ mathcal {r})$。
The well-known theorem of Shalom--Vaserstein and Ershov--Jaikin-Zapirain states that the group $\mathrm{EL}_n(\mathcal{R})$, generated by elementary matrices over a finitely generated commutative ring $\mathcal{R}$, has Kazhdan's property (T) as soon as $n\geq3$. This is no longer true if the ring $\mathcal{R}$ is replaced by a commutative rng (a ring but without the identity) due to nilpotent quotients $\mathrm{EL}_n(\mathcal{R}/\mathcal{R}^k)$. In this paper, we prove that even in such a case the group $\mathrm{EL}_n(\mathcal{R})$ satisfies a certain property that can substitute property (T), provided that $n$ is large enough.
