报告摘要:The Alfvén waves are fundamental wave phenomena in magnetized plasmas and the dynamics of Alfvén waves are governed by a system of nonlinear partial differential equations called the MHD system. In this talk, we study the rigidity aspect of the scattering problem for the MHD equations. We prove that the Alfvén waves must vanish if their scattering fields vanish at infinities. The proof is based on a careful study of the null structure and a family of weighted energy estimates. This is based on the joint work with Prof. Pin Yu.
