Well-rounded sublattices and coincidence site lattices [PDF]
Peter ZeinerA lattice is called well-rounded, if its lattice vectors of minimal length span the ambient space. We show that there are interesting connections between the existence of well-rounded sublattices and coincidence site lattices (CSLs). Furthermore, we count the number of well-rounded sublattices for several planar lattices and give their asymptotic behaviour.View original: http://arxiv.org/abs/1210.0571
