Abstract
Lipshitz, Ozsv\'ath, and Thurston extend the theory of bordered Heegaard Floer homology to compute . Like with the hat theory, their minus invariants provide a recipe to compute knot invariants associated to satellite knots. We combinatorially construct the weighted -modules associated to the -cable. The operations on these modules count certain classes of inductively constructed decorated planar graphs. This description of the weighted -modules provides a combinatorial proof of the structure relations for the modules. We further prove a uniqueness property for the modules we construct: any weighted extensions of the unweighted modules have isomorphic associated type D modules.
