• Isotopy classes for 3-periodic net embeddings 

      Power, Stephen C.; Baburin, Igor A.; Proserpio, Davide M. (Acta Crystallographica Section A, 2020)
      Entangled embedded periodic nets and crystal frameworks are defined, along with their dimension type, homogeneity type, adjacency depth and periodic isotopy type. Periodic isotopy classifications are obtained for various ...
