A new proof for small cancellation conditions of 2-bridge link groups
arXiv:1204.4292
Abstract
In this paper, we give a simple proof for the small cancellation conditions of the upper presentations of 2-bridge link groups, which holds the key to the proof of the main result of [1]. We also give an alternative proof of the main result of [1] using transfinite induction.
