Outline of Final Research Achievements

We obtain high mobility of intrinsic localized mode in anharmonic lattice by constructing a symmetric lattice which has rotational symmetry in the complex normal mode of the corresponding lattice. Highly efficient method for searching a symmetric lattice for FPU lattice is constructed. Therefore we can calculate dynamics of the large particle symmetric lattice. We investigate the structure of ILM and dynamics of ILM in the large symmetric lattices. Adding to this, we obtain a method for constructing symmetric lattices for general lattice systems.
