The　stability　problem　for　the　magnetohydrodynamic　equations　with　partial　or　no　dissipation　has　evoked　a　considerable　interest　in　recent　years.　In　this　paper,　we　establish　the　stability　near　magnetic　hydrostatic　equilibrium　to　the　three-dimensional　magnetic　Bénard　fluid　equations　with　the　mixed　partial　dissipation　involving　viscosity,　resistivity　and　heat　conduction.　Moreover,　we　obtain　the　large-time　behavior　of　the　corresponding　linearized　system.　Our　result　mathematically　verifies　the　stabilization　of　a　background　magnetic　field　on　the　three-dimensional　magnetic　Bénard　fluid.　©　Rocky　Mountain　Mathematics　Consortium.
