Conservation Laws of Some Physical Models via Symbolic Package GeM

الملخص EN

We study the conservation laws of evolution equation, lubrication models, sinh-Poisson equation, Kaup-Kupershmidt equation, and modified Sawada-Kotera equation.

The symbolic software GeM (Cheviakov (2007) and (2010)) is used to derive the multipliers and conservation law fluxes.

Software GeM is Maple-based package, and it computes conservation laws by direct method and first homotopy and second homotopy formulas.
