Conservation laws for some systems of nonlinear partial differential equations via multiplier approach
Summary: The conservation laws for the integrable coupled KdV type system, complexly coupled KdV system, coupled system arising from complex-valued KdV equations in magnetized plasma, Ito integrable system, and Navier Stokes equations of gas dynamics are computed by multipliers approach. First of all, we calculate the multipliers depending on dependent variables, independent variables, and derivatives of dependent variables up to some fixed order. The conservation laws fluxes are computed corresponding to each conserved vector. For all systems, the local conservation laws are established by utilizing the multiplier approach.
