摘要：AbstractWe perform Noether classification of the generalised system of coupled (2 + 1)-dimensional hyperbolic equations, namelyutt-uxx-uyy+P(v)=0,vtt-vxx-vyy+Q(u)=0. Besides this we compute conservation laws corresponding to cases that have Noether symmetries for the underlying coupled hyperbolic system.
