Abstract
We prove that if a fibered knot with genus greater than 1 in a three-manifold has a sufficiently complicated monodromy, then induces a minimal genus Heegaard splitting that is unique up to isotopy, and small genus Heegaard splittings of are stabilizations of . We provide a complexity bound in terms of the Heegaard genus of . We also provide global complexity bounds for fibered knots in the three-sphere and lens spaces.
期刊介绍:
The Journal of Topology publishes papers of high quality and significance in topology, geometry and adjacent areas of mathematics. Interesting, important and often unexpected links connect topology and geometry with many other parts of mathematics, and the editors welcome submissions on exciting new advances concerning such links, as well as those in the core subject areas of the journal.
The Journal of Topology was founded in 2008. It is published quarterly with articles published individually online prior to appearing in a printed issue.
