In this paper, we are concerned with the well-posedness for the compressible Rayleigh-B^nard convection in a bounded domain Ω R2. We prove the local well-posedness of the system with appropriate initial data. This is the result concerning compressible Rayleigh-B^nard convection, before only results about incompressible Rayleigh-B^nard convection were done.展开更多
