本文引入并研究了S∈R和1≤p,r≤∞空间H·L p,r S(Rd)。在H·L p,r S(Rd)族空间中,N-S方程的临界不变空间对应于值S=d p−1.当初始数据属于H·L p,r d p−1(R D)具有d≥2,1≤p<∞,1≤r<∞的临界空间时,我们在L∞([0,T])空间中建立了N-S方程柯西问题局部弱解的存在性.H·L p,rd p−1(Rd)),以及当初值范数足够小时,L∞([0,∞);H·L p,rd p−1(Rd))空间中整体弱解的存在性,其中p˜,∞可取适当的值.
In this note, for s∈ R and 1≤ p, r≤∞, we introduce and study Sobolev–Fourier–Lorentz spaces H˙ L p, r s (R d). In the family spaces H˙ L p, r s (R d), the critical invariant spaces for the Navier–Stokes equations correspond to the value s= d p− 1. When the initial datum belongs to the critical spaces H˙ L p, r d p− 1 (R d) with d≥ 2, 1≤ p<∞, and 1≤ r<∞, we establish the existence of local mild solutions to the Cauchy problem for the Navier–Stokes equations in spaces L∞([0, T]; H˙ L p, r d p− 1 (R d)) with arbitrary initial value, and existence of global mild solutions in spaces L∞([0,∞); H˙ L p, r d p− 1 (R d)) when the norm of the initial value in the Besov spaces B˙ L p˜,∞ d p˜− 1,∞(R d) is small enough, where p˜ may take some suitable values.
