。证明了一个有限生成的Kleinian群N C SO+(, 4)的存在性,使得基本群7tx{Q/N)不是有限生成的,该群自由作用于不带抛物元的不变分量Q C Si。此外,TV是具有无穷多个椭圆元共轭类的Kleinian群No的有限指数子群。
. We prove the existence of a finitely generated Kleinian group N C SO+(, 4) acting freely on an invariant component Q C Si without parabolic elements such that the fundamental group 7tx{Q/N) is not finitely generated. Moreover, TV is a finite index subgroup of a Kleinian group No which has infinitely many conjugacy classes of elliptic elements.
