摘要 研究n(n≥2)维分数阶扩散的MHD-Boussinesq系统.当非负常数α,β及γ满足α≥1/2+n/4,α+β≥1+n/2及α+γ≥n/2时,利用能量方法,得到了MHD-Boussinesq系统全局解的存在唯一性,推广了已有的结果. In this paper,we investigate the n-dimensional(n≥2)MagnetohydrodynamicsBoussinesq system with fractional diffusion.When the nonnegative constantsα,βandγsatisfyα≥1/2+n/4,α+β≥1+n/2 andα+γ≥n/2,by using the energy methods,we obtain the global existence and uniqueness of solution for the system,which generalizes the existing result.
