The left-orderability and the cyclic branched coverings
by
Ying Hu
Louisiana State University

We give a sufficient condition for the fundamental group of the nth cyclic branched covering of S3 along a prime knot K to be left-orderable in terms of representations of the knot group. As an application, we show that for any (p, q) two-bridge knot, with p ≡ 3 mod 4, there are only finitely many cyclic branched coverings whose fundamental groups are not left-orderable. This answers a question posed by D abkowski, Przytycki and Togha.
