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.
