摘要: This paper addresses the 3-D Cauchy problem of a fluid-particle system with a magnetic field. First, the local classical solutions of the linearized model on the sphere $B_{r} $ are obtained by some a priori estimates that do not depend on the radius $r$. Second, the classical solutions of the linearized model in $\mathbb{R}^{3}$ are obtained by combining the continuation and compactness methods. Finally, the classical solutions of the original system are proved by use of the picard iteration argument and the energy method.
