We review numerical results for the relaxation of breathers in Fermi¿Pasta¿Ulam arrays, with a specific focus on the different relaxation channels and their dependence on the interparticle interactions, dimensionality, initial condition, and system parameters1 p.application/pdfeng(c) American Institute of Physics, 2003Física estadísticaTermodinàmicaDifferentiable dynamical systemsFísica matemàticaStatistical physicsThermodynamicsSistemes dinàmics diferenciablesMathematical physicsinfo:eu-repo/semantics/article503885info:eu-repo/semantics/openAccess
