| Abstract: | We present a real space renormalization group (RSRG) method to study the lattice dynamics of a three component Fibonacci (3CF)
quasicrystal. Phonon dispersion relations corresponding to different models of this lattice are obtained. Some features of
the phonon dispersion curves are compared with experiments on real quasicrystal. It is observed that the positions of the
strongest Bragg peaks calculated analytically are in perfect agreement with our RSRG calculations.
