| Research Abstract |
Kadowaki, Nakazawa and Watanabe have studied for the properties of the wave operators with dissipative terms. In the case of the short range perturbations, we proved the existence of the wave operators. In the case of the long range perturbations, the energy of all solutions decays at infinity. The results appeared in Electric Journal of Differential Equation (April 2011). Watanabe studied the interface regularity of the solution for : the rotation system, the self-interactive system (MHD).
