Clock moves and a combinatorial homology

This talk is motivated by an attempt to construct the combinatorial Floer homology via clock moves. For each link diagram, we construct graded homology groups using Kauffman's state sum and clock moves for the Alexander polynomial. While these groups are sometimes invariant under Reidemeister moves, they are, unfortunately, not always invariant under these moves. Nonetheless, we have a graded homology theory for link diagrams which yields the Alexander polynomial when taking graded Euler characteristic. This is joint work with Kerry Luse.
