本篇學術(shù)論文我們主要研究分數(shù)次Navier-Stokes方程在變指標的臨界(?)里的柯西問題.首先,我們討論了變指標的Fourier-Besov空間的一些性質(zhì).我們得到分數(shù)次Navier-Stokes方程在變指標的Fourier-Besov空間上的全局適定性.除此之外,我們也證明了更一般旋轉(zhuǎn)Magneohydrodynamics方程在變指標的Fourier-Besov空間(?)的全局適定性,這個結(jié)果覆蓋了原有的結(jié)果.其次,我們考慮了Navier-Stokes方程在變指標Fourier-Besov-Morrey空間(?)with s(·)=4-2α-3/(p(·))上的柯西問題.得到分數(shù)次Navier-Stokes方程初值在(?)with s(.)=4-2α-3/(p(·))上充分小的全局適定性.
