Boundedness of composition operators associated with mixed homogeneities on Lipschitz spaces
2016
Mathematical Research Letters
This note is motivated by Phong and Stein's work in [PS]. We introduce a new class of Lipschitz spaces associated with mixed homogeneities and characterize these spaces via the Littlewood-Paley theory. We prove that the composition of two Calderón-Zygmund singular integral operators with different homogeneities is bounded on these Lipschitz spaces. Our result answers a question arises in the context of Lipschitz spaces due to the constructions in [MR].
