摘要
By means of Fourier frequency localization and Bony＇s paraproduct decomposition, we study the global existence and the uniqueness of the 2D Leray-α Magneta-hydrodynamics model with zero magnetic diffusivity for the general initial data. In view of the profits bring by the α model, then using the energy estimate in the frequency space and the Logarithmic Sobolev inequality, we obtain the estimate ∫0^t ｜｜△u｜｜L∞ds which is crucial to get the global existence for the general initial data.
