TY - JOUR TI - Infinite many conservation laws of discrete system associated with a 3×3 matrix spectral problem AU - Zhang Sheng AU - Liu Dongdong JN - Thermal Science PY - 2017 VL - 21 IS - 4 SP - 1613 EP - 1619 PT - Article AB - Differential-difference equations are often considered as an alternative approach to describing some phenomena arising in heat/electron conduction and flow in carbon nanotubes and nanoporous materials. Infinite many conservation laws play important role in discussing the integrability of non-linear differential equations. In this paper, infinite many conservation laws of the non-linear differential-difference equations associated with a 3×3 matrix spectral problem are obtained.
