| Abstract: | The long-time behavior of an infinite chain of coupled harmonic oscillators is studied. In addition to a limiting  hydrodynamic (Euler-type) equation, the next approximation is investigated. The corresponding equation is derived. |
| Keywords: | Harmonic oscillators hydrodynamic limit second approximation |
