我们在这里描述新的下界的轨迹的换向器的离散两个生成器组的莫比乌斯变换。这些结果导致尖锐的估计轴之间的距离在一个离散组的椭圆形,因此新的界限的体积双曲流形和orbifolds,将在其他地方讨论。
We describe here new lower bounds for the trace of the commutator of a discrete two-generator group of Möbius transformations. These results lead to sharp estimates for the distance between the axes of elliptics in a discrete group and hence to new bounds for the volume of hyperbolic manifolds and orbifolds that will be discussed elsewhere.
