Abstract
Let Δ be the Kohn sublaplacian on the Heisenberg group \({\mathbb{H}}^n, L =(-\Delta)^\alpha\), \(\frac{2}{3} < \alpha < 1\). In this paper we estimate the L 2-norm of the local maximal function of the unitary group of operators generated by L, by the Sobolev W γ,ε -norm for some γ > 0 and for all ε > 0.
