On the magnetohydrodynamic thermohaline stability problem in completely confined fluids

The amenability of the linear stability analysis for the magnetohydrodynamic thermal stability problem in completely confined fluids carried by Gupta and Dhiman [J. Math. Anal. Appl. 262 (2001) 221–228] for extension to the magnetohydrodynamic thermohaline stability problems of Veronis and Stern type configurations is shown to yield some general qualitative mathematical results concerning the character of marginal state, stability of oscillatory motions and limitations on the oscillatory motions of growing amplitude, which to the best of our knowledge do not appear to have been reported earlier in the literature on thermohaline stability problem with the same degree of generality.  2002 Elsevier Science (USA).
