Let $s\in \mathbb{R}$ and $0<p\leqslant \infty$ . The fractional Fock–Sobolev spaces $F_{\mathscr{R}}^{s,p}$ are introduced through the fractional radial derivatives $\mathscr{R}^{s/2}$ . We describe explicitly the reproducing kernels for the fractional Fock–Sobolev spaces $F_{\mathscr{R}}^{s,2}$ and then get the pointwise size estimate of the reproducing kernels. By using the estimate, we prove that the fractional Fock–Sobolev spaces $F_{\mathscr{R}}^{s,p}$ are identified with the weighted Fock spaces $F_{s}^{p}$ that do not involve derivatives. So, the study on the Fock–Sobolev spaces is reduced to that on the weighted Fock spaces.

让$s\in \mathbb{R}$ 和$0<p\leqslant\infty$ . 分数 Fock–Sobolev 空间$F_{\mathscr{R}}^{s,p}$ 通过分数径向导数引入$\mathscr{R}^{s/2}$ . 我们明确地描述了分数 Fock–Sobolev 空间的再生核$F_{\mathscr{R}}^{s,2}$ 然后得到再生内核的逐点大小估计。通过使用估计,我们证明了分数 Fock–Sobolev 空间$F_{\mathscr{R}}^{s,p}$ 用加权 Fock 空间标识$F_{s}^{p}$ 不涉及衍生品。因此,对 Fock-Sobolev 空间的研究简化为对加权 Fock 空间的研究。
