AI总结:
本文为CAT(0)空间中格点的离散子群建立公共共轭子群框架,证明Greenberg-Shalom猜想在一般性下失败,并分析Burger-Mozes例子显示其公共共轭子群离散。
摘要:
我们为CAT(0)空间的等距群中格点的离散子群的公共共轭子群建立了一个框架。我们证明了关于Zariski稠密子群与格点的公共共轭子群的离散性的Greenberg-Shalom猜想在此一般性下不成立,即使施加强有限性条件也是如此。我们分析了Burger和Mozes在此背景下的一些例子,并表明它们具有离散的公共共轭子群。
英文摘要:
We develop a framework for common commensurators of discrete subgroups of lattices in isometry groups of CAT(0) spaces. We show that the Greenberg-Shalom hypothesis about discreteness of common commensurators of Zariski dense subgroups and lattices fails in this generality, even if one imposes strong finiteness conditions. We analyze some examples due to Burger and Mozes in this context and show that they have discrete common commensurator.
