Abstract

Using an argument of Baldwin--Hu--Sivek, we prove that if KK is a hyperbolic fibered knot with fiber FF in a closed, oriented 33--manifold YY, and HFK^(Y,K,[F],g(F)1)\widehat{HFK}(Y,K,[F], g(F)-1) has rank 11, then the monodromy of KK is freely isotopic to a pseudo-Anosov map with no fixed points. In particular, this shows that the monodromy of a hyperbolic L-space knot is freely isotopic to a map with no fixed points.
