Abstract
A model from electro-magneto-hydrodynamics describing a completely ionized gas, a plasma, is studied. Local well posedness of the problem in time-weighted \(L_p\) spaces is obtained by means of maximal regularity of the linearized problem, and the induced local semiflow in the proper state space is constructed. If the underlying domain is bounded and simply connected, based on the principle of linearized stability, it is shown that the trivial solution of the problem is exponentially stable. Moreover, if the orbit of a solution is relatively compact in the state space, the solution exists globally, and it converges to the trivial equilibrium.
