Kato-Ponce estimates for fractional sublaplacians (2107.10235v1)
Published 21 Jul 2021 in math.AP and math.CA
Abstract: We give a proof of commutator estimates for fractional powers of the sublaplacian on the Heisenberg group. Our approach is based on pointwise and $Lp$ estimates involving square fractional integrals and Littlewood-Paley square functions.
