Abstract

In this article, we study the electromagnetic fluid system in three-dimensional whole space R3. Under assumption of small initial data, we establish the unique global solution by energy method. Moreover, we obtain the time decay rates of the higher-order spatial derivatives of the solution by combining the Lp - Lq estimates for the linearized equations and an elaborate energy method when the L1-norm of the perturbation is bounded.
