摘要
得到了若干M bius群中相应性质在^U(1,n;C)中的推广,并由此建立了^U(1,n;C)上的类Jorgensen不等式.利用此不等式得到了^U(1,n;C)中有限生成子群的一条离散准则.
Some properties held in Mobius group are generalized to the cases of (1,n;C). By using the obtained results, the generalized Jorgensen's inequalities in (1,n;C) are established and a discreteness criterion for finitely generated subgroups of (1,n;C) is obtained.
