Boundedness of Marcinkiewicz integrals on Hardy spaces H^p over non-homogeneous metric measure spaces [PDF]

open access: yesJournal of Mathematical Inequalities, 2018
Summary: Under the assumption that \((\mathcal{X}, d, \mu)\) is a non-homogeneous metric measure space, the authors prove that the Marcinkiewicz integral operator is bounded from the molecular Hardy space \(\tilde{H}_{mb,\rho}^{p,q\gamma,\varepsilon}(\mu)\)(or the atomic Hardy space \(\tilde{H}_{atb,\rho}^{p,q,\gamma}(\mu))\) into the Lebesgue space ...

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

open access: yesAIMS 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 ...

Vector-valued non-homogeneous $Tb$ theorem on metric measure spaces

open access: yesRevista Matemática Iberoamericana, 2012
We prove a vector-valued non-homogeneous Tb theorem on certain quasimetric spaces equipped with what we call an upper doubling measure. Essentially, we merge recent techniques from the domain and range side of things, achieving a

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

open access: yesJournal of Mathematical Analysis and Applications, 2012
The authors discuss the boundedness of Calderón-Zygmund operators on non-homogeneous metric measure spaces. They prove that the boundedness of Calderón-Zygmund operators on \(L^2\) is equivalent to either the boundedness of \(T\) from the atomic Hardy space \(H^1\) to \(L^{1,\infty}\) or from \(H^1\) to \(L^1\) on the measure space \((X,d,\mu)\) in the

Boundedness for iterated commutators of multilinear singular integrals of Dini's type on non-homogeneous metric measure spaces [PDF]

open access: yesSCIENTIA SINICA Mathematica, 2017
Assume that $(\mathcal X, d, \mu)$ is a geometrically doubling metric space and the measure $\mu$ is an upper doubling measure. This paper focuses on studying the boundedness of iterated commutators, which is generated by multilinear singular integral operators with the function $\bm{b}$ in $\mathrm{RBMO}(\mu)$.

Permanence of metric fractals

open access: yesElectronic Journal of Differential Equations, 2007
The paper studies energy functionals on quasimetric spaces, defined by quadratic measure-valued Lagrangeans. This general model of medium, known as metric fractals, includes nested fractals and sub-Riemannian manifolds.
