Knot theory and cluster algebras
Abstract
We establish a connection between knot theory and cluster algebras via representation theory. To every knot diagram (or link diagram), we associate a cluster algebra by constructing a quiver with potential. The rank of the cluster algebra is , where is the number of crossing points in the knot diagram. We then construct indecomposable modules over the Jacobian algebra of the quiver with potential. For each , we show that the submodule lattice is isomorphic to the corresponding lattice of Kauffman states. We then give a realization of the Alexander polynomial of the knot as a specialization of the -polynomial of , for every . Furthermore, we conjecture that the collection of the forms a cluster in the cluster algebra whose quiver is isomorphic to the opposite of the initial quiver, and that the resulting cluster automorphism is of order two.
