Subperiodic groups and bounded automorphisms of periodic graphs
Igor A. Baburin
A subperiodic group is a group of motions of -dimensional Euclidean space which contains a translation lattice of rank as a subgroup of finite index. A cla…
On colourings of cubic lattices
Igor A. Baburin
Given the integral lattice in -dimensional Euclidean space, partitions of the lattice nodes into orbits of finite-index subgroups of have been computed for $d \…
Short presentations for crystallographic groups
Igor A. Baburin
A practical approach is proposed to construct short presentations for Euclidean crystallographic groups in terms of generators and relations. For our purposes a short presentation…
Isotopy classes of 3-periodic net embeddings
Igor Baburin, Stephen Power, Davide Proserpio
Entangled embedded periodic nets and crystal frameworks are defined, along with their dimension type, homogeneity type, adjacency depth and periodic isotopy type. We obtain periodi…
