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

Herz type Hardy spaces on non-homogeneous metric measure space [PDF]

open access: bronzeSCIENTIA SINICA Mathematica, 2018
Let $(\mathcal{X},d,\mu)$ be a non-homogeneous metric measure spacesatisfying both the geometrically doubling and the upper doublingconditions. In this paper, the Herz spaces on the non-homogeneousmetric measure space are introduced. Then the decomposition of theHerz space by the central blocks is obtained.

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

open access: diamondJournal 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 ...

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

open access: bronzeSCIENTIA 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 $\mathrm{RBMO}(\mu)$.

Weak estimates for the maximal and Riesz potential operators on non-homogeneous central Morrey type spaces in L^1 over metric measure spaces

open access: bronzeAnnales Academiae Scientiarum Fennicae Mathematica, 2020
The authors provide weak \(M^{1,q,a}(X)\)-estimates for the maximal and Riesz potential operators. Under certain assumptions on the growth of the measures of balls in \(X\) (which hold in the Euclidean setting), it is shown in Theorems 3.3 and 4.6 that the maximal operator and the Riesz potential operator are bounded from \(M^{1,q,a}(X)\) to \(WM ...

Initial Conditions in String Cosmology [PDF]

open access: yes, 1998
We take a critical look at a recent conjecture concerning the past attractor in the pre-big-bang scenario. We argue that the Milne universe is unlikely to be a general past attractor for such models and support this with a number of examples.Comment: 10 ...
