Abstract
We study the stability problem of steady solutions to the semi-stationary Boussinesq equations in the strip domain R2×(0,1). For an equilibrium state with any general steady solution θe which satisfies ϑe > m > 0, we show the global existence and asymptotic behavior of solutions to the system with the no-slip boundary condition when the initial temperature is close enough to it. Thus such a steady solution is asymptotically stable, which reflects the well-known phenomenon of Rayleigh-Taylor stability.
期刊介绍：
Since 1960, the Journal of Mathematical Physics (JMP) has published some of the best papers from outstanding mathematicians and physicists. JMP was the first journal in the field of mathematical physics and publishes research that connects the application of mathematics to problems in physics, as well as illustrates the development of mathematical methods for such applications and for the formulation of physical theories.
The Journal of Mathematical Physics (JMP) features content in all areas of mathematical physics. Specifically, the articles focus on areas of research that illustrate the application of mathematics to problems in physics, the development of mathematical methods for such applications, and for the formulation of physical theories. The mathematics featured in the articles are written so that theoretical physicists can understand them. JMP also publishes review articles on mathematical subjects relevant to physics as well as special issues that combine manuscripts on a topic of current interest to the mathematical physics community.
JMP welcomes original research of the highest quality in all active areas of mathematical physics, including the following:
Partial Differential Equations
Representation Theory and Algebraic Methods
Many Body and Condensed Matter Physics
Quantum Mechanics - General and Nonrelativistic
Quantum Information and Computation
Relativistic Quantum Mechanics, Quantum Field Theory, Quantum Gravity, and String Theory
General Relativity and Gravitation
Dynamical Systems
Classical Mechanics and Classical Fields
Fluids
Statistical Physics
Methods of Mathematical Physics.
