Natural algebra action on matchings for alternating Kasteleyn matrices
Natural algebra action on matchings for alternating Kasteleyn matrices
Let be a nonsingular alternating matrix, and let be the matrix-algebra deformation of defined by the twisted relations in the paper. Let be a planar graph with nonempty matching set , and suppose that is a Kasteleyn matrix of . Kasteleyn algebra-action conjecture. There is a natural action of on , possibly depending on how is embedded in the plane. Such an action would provide the algebraic structure underlying the proposed quantum-bijection interpretation of perfect matchings. The source gives no proof or resolution, so the conjecture remains open.
