Vanishing of $L^{2}$ -Betti numbers and failure of acylindrical hyperbolicity of matrix groups over rings

Feng Ji, Shengkui Ye

Let $R$ be an infinite commutative ring with identity and $n \geq 2$ be an integer. We prove that for each integer $i = 0, 1, \dots, n - 2,$ the $L^{2}$ -Betti number $b_{i}^{(2)} (G) = 0,$ …
