The projections of lattices may be used as models of quasicrystals, and the particular affine extension of the H2 symmetry as a subgroup of A4, discussed in this work, presents a different perspective on fivefold symmetric quasicrystallography. Affine H2 is obtained as the subgroup of affine A4. The infinite discrete group with local dihedral symmetry of order 10 operates on the Coxeter plane of the root and weight lattices of A4 whose Voronoi cells tessellate the 4D Euclidean space possessing…

The Cell Structures of Certain Lattices

The most important lattices in Euclidean space of dimension n≀ 8 are the lattices An (nβ‰₯ 2), Dn (nβ‰₯ 4), En (n = 6, 7, 8) and their duals. In this paper we determine the cell structures of all these…

Aperiodic Order. Vol 1. A Mathematical Invitation

This first volume provides a graduate-level introduction to the many facets of this relatively new area of mathematics, known as the theory of aperiodic order, and provides a systematic exposition of the mathematical theory of kinematic diffraction.
