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 ...

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

open access: closedTaiwanese 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 ...

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

open access: closedProceedings 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 Strongly Singular Integral Operators on Non-Homogenous Metric Measure Spaces

Analysis Mathematica, 2022
Our spaces are subsets of \(\mathbb{R}^n\). Singular integral operators have been studied on spaces of homogeneous type in which the measure on the space is doubling, (i.e. that there is a constant \(C>0\) such that \(\mu(B(x, 2r) \leq C \mu B(x,r)\), for all \(x \in\)supp\(\ \mu\), and \(r>0\)).
