摘要

This paper investigates global stability of the three-dimensional incompressible magnetic Bénard system with horizontal dissipation. The lack of dissipation in the vertical direction poses challenges for studying global stability. We first establish global stability of 3D magnetic Bénard system near the hydrostatic balance. Furthermore, the optimal time-decay rates of the global solution and its partial derivatives are established when the initial data also belongs to homogeneous negative Sobolev spaces.
