Abstract

Let L 1 = −Δ + V be a Schr:dinger operator and let L 2 = (−Δ)2 + V 2 be a Schrödinger type operator on ℝ n (n ⩾ 5), where V≠ 0 is a nonnegative potential belonging to certain reverse Hölder class B s for sn/2. The Hardy type space \(H_{{L_2}}^1\) is defined in terms of the maximal function with respect to the semigroup \(\left\{ {{e^{ - t{L_2}}}} \right\}\) and it is identical to the Hardy space \(H_{{L_1}}^1\) established by Dziubański and Zienkiewicz. In this article, we prove the L p -boundedness of the commutator R b = bRf - R(bf) generated by the Riesz transform \(R = {\nabla ^2}L_2^{ - 1/2}\), where \(b \in BM{O_\theta }(\varrho )\), which is larger than the space BMO(ℝ n ). Moreover, we prove that R b is bounded from the Hardy space \(H_{\mathcal{L}_1 }^1 \) into weak \(L_{weak}^1 (\mathbb{R}^n )\).
