| 中文摘要: |
| 作者研究了具有垂直分数阶耗散νΛ22αu和分数阶磁扩散ηΛ2βb的二维不可压缩磁流体动力学方程解的稳定性. 对于该系统, 文[Feng W, Wang W, Wu J. Stability for a system of the 2D incompressible MHD equations with fractional dissipation [J]. J Math Fluid Mech, 2024, 26(4):57]建立了在Sobolev空间H3(R2)上的稳定性. 通过引入新的带有分数阶导数的各向异性不等式, 将其稳定性结果推广至更低的正则性空间H2(R2). |
| 英文摘要: |
| In this paper, the authors study the stability of solutions of the two-dimensional incompressible magnetohydrodynamic equations with fractional vertical dissipation νΛ22αu and fractional magnetic diffusion ηΛ2βb. For this system, [Feng W, Wang W, Wu J. Stability for a system of the 2D incompressible MHD equations with fractional dissipation [J]. J Math Fluid Mech, 2024, 26(4):57] established the stability in the Sobolev space H3(R2). The authors extend the result to the lower regularity space H2(R2) by introducing new anisotropic inequalities involving fractional derivatives. |
