An interpolation theorem for sublinear operators on non-homogeneous metric measure spaces

open access: hybridBanach Journal of Mathematical Analysis, 2012
Let $({\mathcal X}, d, )$ be a metric measure space and satisfy the so-called upper doubling condition and the geometrically doubling condition. In this paper, the authors establish an interpolation result that a sublinear operator which is bounded from the Hardy space $H^1( )$ to $L^{1,\,\infty}( )$ and from $L^\infty( )$ to the BMO-type space ${\

Boundedness of maximal Calderón–Zygmund operators on non-homogeneous metric measure spaces [PDF]

open access: greenProceedings of the Royal Society of Edinburgh: Section A Mathematics, 2014
Let (X, d, μ) be a metric measure space and let it satisfy the so-called upper doubling condition and the geometrically doubling condition. We show that, for the maximal Calderón–Zygmund operator associated with a singular integral whose kernel satisfies the standard size condition and the Hörmander condition, its Lp(μ)-boundedness with p ∈ (1, ∞) is ...

Boundedness of Calderón–Zygmund operators on non-homogeneous metric measure spaces: Equivalent characterizations

open access: bronzeJournal of Mathematical Analysis and Applications, 2011
AbstractLet (X,d,μ) be a metric measure space satisfying the upper doubling and the geometrically doubling conditions in the sense of T. Hytönen. In this paper, the authors prove that the boundedness of a Calderón–Zygmund operator T on L2(μ) is equivalent to either of the boundedness of T from the atomic Hardy space H1(μ) to L1,∞(μ) or from H1(μ) to L1(

Commutators of multilinear $ \theta $-type generalized fractional integrals on non-homogeneous metric measure spaces

open access: goldAIMS Mathematics, 2022
<abstract><p>Let $ {\mathcal{I}_{\alpha, m}} $ be the multilinear $ \theta $-type generalized fractional integrals and $ \vec{b}_{\sigma} $ be the vector with each $ b_{\sigma_{i}} \in \widetilde{{\rm{RBMO}}}\left(\mu\right) $. The boundedness for $ {\mathcal{I}_{\alpha, m}} $ and the iterated multi-commutators $ {\mathcal{I}_{\alpha, m ...
