Surface embedding, topology and dualization for spin networks

Show affiliations


Spin networks are graphs derived from 3nj symbols of angular momentum. The surface embedding, the topology and dualization of these networks are considered. Embeddings into compact surfaces include the orientable sphere S2 and the torus T, and the not orientable projective space P2 and Klein's bottle K. Two families of 3nj graphs admit embeddings of minimal genus into S2 and P2. Their dual 2-skeletons are shown to be triangulations of these surfaces.
