A Characterization of Hajłasz-Sobolev and Triebel-Lizorkin Spaces via Grand Littlewood-Paley Functions

Pekka Koskela, Dachun Yang, Yuan Zhou

In this paper, we establish the equivalence between the Hajłasz-Sobolev spaces or classical Triebel-Lizorkin spaces and a class of grand Triebel-Lizorkin spaces on Euclidean spaces…

New Orlicz-Hardy Spaces Associated with Divergence Form Elliptic Operators

Renjin Jiang, Dachun Yang

Let $L$ be the divergence form elliptic operator with complex bounded measurable coefficients, $ω$ the positive concave function on $(0, \infty)$ of strictly critical lower type $p_…

Predual Spaces of Banach Completions of Orlicz-Hardy Spaces Associated with Operators

Renjin Jiang, Dachun Yang

Let $L$ be a linear operator in $L^{2} (R^{n})$ and generate an analytic semigroup ${e^{- t L}}_{t \geq 0}$ with kernels satisfying an upper bound of Poisson type, whose decay…

Radial Maximal Function Characterizations of Hardy Spaces on RD-Spaces and Their Applications

Dachun Yang, Yuan Zhou

Let $X$ be an RD-space with $μ (X) = \infty$ , which means that $X$ is a space of homogeneous type in the sense of Coifman and Weiss and its measure ha…

Characterizations of BMO Associated with Gauss Measures via Commutators of Local Fractional Integrals

Liguang Liu, Dachun Yang

Let $d γ (x) \equiv π^{- n /2} e^{- ∣ x ∣^{2}} d x$ for all $x \in R^{n}$ be the Gauss measure on $R^{n}$ . In this paper, the authors establish the characterizations of the space B…

Boundedness of Sublinear Operators on Product Hardy Spaces and Its Application

Der-Chen Chang, Dachun Yang, Yuan Zhou

Let $p \in (0, 1]$ . In this paper, the authors prove that a sublinear operator $T$ (which is originally defined on smooth functions with compact support) can be extended as a bounded…
