论文摘要
在本文中,我们将讨论由$ {\ rm psp} $ {\ rm psp}(2,1)$的两个海森伯格翻译产生的组,并确定何时免费。我们改善了Xie,Wang,Jiang在Canad中给出的结果。数学。公牛。 $ 56(2013),881-889。$,并从该衍生的结果中获得$ {\ rm psp}(2,1)$ case的结果。
In this paper, we will discuss the groups generated by two Heisenberg translations of ${\rm PSp}(2,1)$ and determine when they are free. We improve a result given in \cite{xwy} by Xie, Wang, Jiang in Canad. Math. Bull. $56(2013), 881-889.$ and from that derive result for the ${\rm PSp}(2,1)$ case.
