| 摘 要： | 该文讨论了在真空远场的密度条件下,二维不可压零磁耗散磁流体力学方程组柯西问题的局部适定性.在初始密度和磁场具有一定的衰减性时,证明了磁流体方程具有唯一的局部强解.当初值满足兼容性条件和适当的正则性条件时,该强解就是经典解.除此之外,文中还给出了一个仅与磁场有关的爆破准则.

| Abstract: | In this paper,we investigate the Cauchy problem of the nonhomogeneous incompressible and non-resistive MHD on R2 with vacuum as far field density and prove that the 2D Cauchy problem has a unique local strong solution provided that the initial density and magnetic field decay not too slow at infinity.Furthermore,if the initial data satisfy some additional regularity and compatibility conditions,the strong solution becomes a classical one.Moreover,we also establish a blowup criterion which depends only on the Magnetic fields. |
