Abstract

When k is a field, type D structures over the algebra k[u,v]∕(uv) are equivalent to immersed curves decorated with local systems in the twice-punctured disk. Consequently, knot Floer homology, as a type D structure over k[u,v]∕(uv), can be viewed as a set of immersed curves. With this observation as a starting point, given a knot K in S3, we realize the immersed curve invariant HF (S3\∘ν(K)) of Hanselman, Rasmussen and Watson by converting the twice-punctured disk to a once-punctured torus via a handle attachment. This recovers a result of Lipshitz, Ozsváth and Thurston calculating the bordered invariant of S3\∘ν(K)) in terms of the knot Floer homology of K.
