Abstract
The connection of symmetry groups, their irreducible and band represen tations for the models of finite and infinite crystals is considered i n detail. The relation between localized (electronic and vibrational) states of finite and infinite crystals is studied on models. It is fou nd that the Wannier states of an infinite crystal are reproduced well by Wannier states of cyclic systems with size slightly exceeding the r egion of their localization.
