摘要
We describe here new lower bounds for the trace of the commutator of a discrete two-generator group of Mobius 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.
