Abstract
In this paper, we consider the Schrödinger type operator \({H = (-\Delta _{\mathbb {H}}^n)^2 +V ^{2}}\), where the nonnegative potential V belongs to the reverse Hölder class \({B_{{q}_{1}}\, {\rm for}\, q_{1}\geq {\frac {Q}{ 2}},Q \geq 6}\), and \({\Delta_{\mathbb {H}^n}}\) is the sublaplacian on the Heisenberg group \({\mathbb {H}^n}\). An L p estimate and a weak type L 1 estimate for the operator \({\nabla^4_{\mathbb {H}^n} H^{-1}}\) when \({V \in B_{{q}_{1}}}\) for \({1 < p \leq \frac{q_{1}}{2}}\) are obtained.
