Predual Spaces of Hardy Spaces Related to Fractional Schrödinger Operators

Qiumeng Li, Haibo Lin, Sibei Yang

Let $n\in \mathbb{N}$ and $\alpha \in (0,\min \{2,n\})$. For any $a\in [a^{\ast },\infty )$, the fractional Schrödinger operator $L_{\alpha }$ is defined by \begin{equation*} L_α:=(-Δ)^{α/2}+a{|x|}^{-α}…
