Embedded surfaces with infinite cyclic knot group
Anthony Conway, Mark Powell
We study locally flat, compact, oriented surfaces in -manifolds whose exteriors have infinite cyclic fundamental group. We give algebraic topological criteria for two such surfa…

Twisted signatures of fibered knots
Anthony Conway, Matthias Nagel
This paper concerns twisted signature invariants of knots and 3-manifolds. In the fibered case, we reduce the computation of these invariants to the study of the intersection form…
