Abstract
The stability of symmetric and anti-symmetric localized modes in the c ase of ''hard'' anharmonicity is considered. In the high-frequency lim it the infinite chain is replaced by a ring of four particles. The sol utions of this system and their stability are found analytically and t heir relation to intrinsic localized modes are considered. The applica bility of results and the relation between localized modes and soliton s are also discussed.
