Equivalence of the generalised grid and projection methods for the construction of quasiperiodic tilings

Abstract

The two main techniques for the generation of quasipcriodic tilings.,de Bruijn's grid method and the projection formalism, are generalised. A very broad class or quasi periodic tilings is obtained in this way. The two generalised methods are Shown to be equivalent. The standard calculation of Fourier spectra is extended to the whole general class of tilings. Various upplications are discussed.
