Seifert fibred knot manifolds

J.A.Hillman

Abstract

We consider the question of when is the closed manifold obtained by elementary surgery on an $n$-knot Seifert fibred over a 2-orbifold. After some observations on the classical case, we concentrate on the cases $n=2$ and 3. We have found a new family of 2-knots with torsion-free, solvable group, overlooked in earlier work. We show also that there are no aspherical Seifert fibred 3-knot manifolds. We know of no higher dimensional examples.

Keywords: knot, Seifert fibred, $0$-framed surgery.
