AI 中文摘要
基于Kassel–Loday和Zelmanov–Zhang的工作,我们证明合适Bestvina–Brady群的复群代数的Steinberg李代数为$FP_2$型且非有限表示,这也让我们能回答李代数的(同调)0-1-2问题。
英文摘要
Building on work of Kassel--Loday and Zelmanov--Zhang, we show that a Steinberg Lie algebra of the complex group algebra of a (suitable) Bestvina--Brady group is of type $FP_2$ and is not finitely presented. This also allows us to answer the (homological) $0$-$1$-$2$ question for Lie algebras.
