On left-orderable fundamental groups and Dehn surgeries on knots

Geometric Topology 2013-06-18 v3

Abstract

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