关于左序基本群和纽结上的Dehn运算

On left-orderable fundamental groups and Dehn surgeries on knots

Anh T. Tran

摘要:

我们证明了当斜率$r$满足一定条件时,对一大类两桥纽结进行$r$ -手术所得到的流形具有左序基本群.这一结果为Boyer,Gordon和Watson关于$L$ -空间及其基本群的左序性的猜想提供了有力的证据.

英文摘要:

We show that the resulting manifold by $r$-surgery on a large class of two-bridge knots has left-orderable fundamental group if the slope $r$ satisfies certain conditions. This result gives a supporting evidence to a conjecture of Boyer, Gordon and Watson that relates $L$-spaces and the left-orderability of their fundamental groups.
