摘要：

The stability of symmetric and anti-symmetric localized modes in the case of ''hard'' anharmonicity is considered. In the high-frequency limit the infinite chain is replaced by a ring of four particles. The solutions of this system and their stability are found analytically and their relation to intrinsic localized modes are considered. The applicability of results and the relation between localized modes and solitons are also discussed.
