TY - JOUR A1 - García-Escudero, Juan T1 - Substitutional sequences for patterns with nine-fold symmetry Y1 - 1997 SN - 02179849 UR - http://hdl.handle.net/11268/6260 AB - Two classes of self-similar planar patterns with nine-fold symmetry are studied. They can be derived with the help of a construction due to Nischke and Danzer. One of them has Bragg spectrum and therefore it is of interest in quasicrystal theory. An interpretation in terms of substitutional sequences is proposed. KW - Física nuclear KW - Física estadística KW - Física molecular KW - Física nuclear LA - eng ER -
