Gordon–Lidman conjecture on cyclic branched covers of satellite knots

Let KK be a prime satellite knot in S3S^3, and for each positive integer nn let Σn(K)\Sigma_n(K) denote the nn-fold cyclic branched cover of S3S^3 branched over KK. A Gordon–Lidman conjecture. Every cyclic branched cover Σn(K)\Sigma_n(K) is excellent. Here, excellent means that the manifold is neither an LL-space nor has a non-left-orderable fundamental group, in the terminology used for cyclic branched covers; the statement is presented as an expected generalization of known results for torus knots, and its resolution is not supplied in the source.
