勒当引入了Besov型空间和Triebel-Lizorkin型空间,统一和推广了Besov空间、Triebel-Lizorkin空间和Q空间.然后,我们建立了这些新的空间在Frazier和Jawerth的意义上的变换特征。利用的-变换刻画,得到了它们的嵌入和提升性质;此外,对于适当的τ,我们还建立了的光滑原子和分子分解刻画.对于,和,通过Hausdorff容性,我们引入了一类Hardy-Hausdorff空间,并证明了的对偶空间是正义的,其中t ′表示的共轭指数。
Letand. We introduce Besov-type spacesforand Triebel–Lizorkin-type spaces, which unify and generalize the Besov spaces, Triebel–Lizorkin spaces andQspaces. We then establish the-transform characterization of these new spaces in the sense of Frazier and Jawerth. Using the-transform characterization of, we obtain their embedding and lifting properties; moreover, for appropriate τ, we also establish the smooth atomic and molecular decomposition characterizations of. For,and, via the Hausdorff capacity, we introduce certain Hardy–Hausdorff spacesand prove that the dual space ofis just, wheret′ denotes the conjugate index of.
