报告题目: Temporal Decay of the Generalized MHD Equations in Some Critical Spaces
报告内容: In this talk I will present the decay estimate of solutions to the 3D generalized magnetohydrodynamic system in the critical space with 1/2≤α≤1 for small initial data. In 2D case with α=1, the global well-posedness of a strong solution in the Lei-Lin space with any initial data in is established. Furthermore, the uniqueness of the strong solution in and the Leray-Hopf weak solution in is proved. I also present the stability problem on perturbation near a physically steady state solution of the 3D generalized incompressible magnetohydrodynamic system in Lei-Lin space. The global stability and analytic estimates for small perturbation are established by the semigroup method in the critical space with , where linear terms from perturbation incur much difficulty.
