论文摘要
我们研究besov-morrey空间$ \ mathcal {n}^{s} _ {u，p，q}（\ mathbb {r}^{d}）$，并显示在某些条件下，这些空间可以以高阶差异来表征这些空间。此外，我们证明了一些上述条件也是必要的。
We study the Besov-Morrey spaces $ \mathcal{N}^{s}_{u,p,q}(\mathbb{R}^{d}) $ and show that under certain conditions on the parameters these spaces can be characterized in terms of higher-order differences. Furthermore we prove that some of the mentioned conditions are also necessary.
