A characterization of Hardy spaces associated with certain Schrödinger operators

Jacek Dziubański, Jacek Zienkiewicz

Let $\{K_t{\}}_{t>0}$ be the semigroup of linear operators generated by a Schrödinger operator $-L=\Delta -V(x)$ on ${\mathbb{R}}^d$, $d\ge 3$, where $V(x)\ge 0$ satisfies $Δ^{-1} V\in L^\…
