Generalized Fractional Integrals and Their Commutators over Non-homogeneous Metric Measure Spaces [PDF]

open access: green, 2013
Let $({\mathcal X},d,\mu)$ be a metric measure space satisfying both the upper doubling and the geometrically doubling conditions. In this paper, the authors establish some equivalent characterizations for the boundedness of fractional integrals over $({\

COMMUTATORS OF MULTILINEAR SINGULAR INTEGRAL OPERATORS ON NON-HOMOGENEOUS METRIC MEASURE SPACES [PDF]

open access: hybridTaiwanese Journal of Mathematics, 2015
Let $(X,d, )$ be a metric measure space satisfying both the geometrically doubling and the upper doubling measure conditions, which is called non-homogeneous metric measure space. In this paper, via a sharp maximal operator, the boundedness of commutators generated by multilinear singular integral with $RBMO( )$ function on non-homogeneous metric ...

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

open access: bronzeRevista 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 Tb ...

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(

Boundedness of Calderón-Zygmund Operators on Non-homogeneous Metric Measure Spaces [PDF]

open access: greenCanadian Journal of Mathematics - Journal Canadien de Mathematiques, 2010
Let $\left( \text{ }\!\!\chi\!\!\text{ ,}\,d,\,\mu \right)$ be a separable metric measure space satisfying the known upper doubling condition, the geometrical doubling condition, and the non-atomic condition that $\mu \left( \left\{ x \right\} \right)\,=\

Spaces of Type BLO on Non-homogeneous Metric Measure Spaces

open access: green, 2010
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 introduce the space ${\mathop\mathrm{RBLO}}( )$ and prove that it is a subset of the known space ${\mathop\mathrm{RBMO}}( )$ in this context.

Non-homogeneous Tb Theorem and Random Dyadic Cubes on Metric Measure Spaces [PDF]

open access: closedJournal of Geometric Analysis, 2011
We prove a Tb theorem on quasimetric spaces equipped with what we call an upper doubling measure. This is a property that encompasses both the doubling measures and those satisfying the upper power bound (B(x,r)) \le Cr^d. Our spaces are only assumed to satisfy the geometric doubling property: every ball of radius r can be covered by at most N balls ...
