A characterization theorem in hydromagnetic double-diffusive convection coupled with cross diffusions

In the present paper, the governing equations of hydromagnetic double-diffusive convection problem of Veronis' type coupled with cross diffusion are linearized by the construction of a proper transformation and the relationship between various energies is established. The analysis made shows that total kinetic energy associated with a disturbance is greater than the sum of its total magnetic and concentration energies in the parameter regime. The result is valid for quite general boundary conditions.
