Hausdorff operators on the weighted Herz-type Hardy spaces

open access: yes, 2016
In this paper, we study the high-dimensional Hausdorff operators on the weighted Herz-type Hardy spaces and obtain some substantial extensions from the previous results in [3].

Integral means and boundary limits of Dirichlet series [PDF]

open access: yes, 2007
We study the boundary behavior of functions in the Hardy spaces HD^p for ordinary Dirichlet series. Our main result, answering a question of H. Hedenmalm, shows that the classical F. Carlson theorem on integral means does not extend to the imaginary axis

Elliptic Riesz operators on the weighted special atom spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 19, Issue 1, Page 15-18, 1996., 1995
In this paper we study the boundedness and convergence of and , the elliptic Riesz operators and the conjugate elliptic Riesz operators of order s > 0, on the weighted special atom space B(ω).

Calderón-Hardy Spaces with variable exponents and the solution of the equation Δ^m F = f for f ∈ H^p(⋅)(ℝ^n)

open access: yes, 2016
In this article we define the Calderón-Hardy spaces with variable exponents on Rn , H p(.) q,γ (Rn) , and we show that for m∈N the operator Δm is a bijective mapping from H p(.) q,2m(R) onto Hp(.)(Rn) .

Optimal estimates for harmonic functions in the unit ball

open access: yes, 2011
We find the sharp constants $C_p$ and the sharp functions $C_p=C_p(x)$ in the inequality $$|u(x)|\leq \frac{C_p}{(1-|x|^2)^{(n-1)/p}}\|u\|_{h^p(B^n)}, u\in h^p(B^n), x\in B^n,$$ in terms of Gauss hypergeometric and Euler functions.

A Note on Div-Curl Lemma [PDF]

open access: yes, 2007
2000 Mathematics Subject Classification: 42B30, 46E35, 35B65.We prove two results concerning the div-curl lemma without assuming any sort of exact cancellation, namely the divergence and curl need not be zero, and $$div(u^−v^→) ∈ H^1(R^d)$$ which include

Bilinear pseudo-differential operators with exotic symbols, II

open access: yes, 2018
The boundedness from $H^p \times L^2$ to $L^r$, $1/p+1/2=1/r$, and from $H^p \times L^{\infty}$ to $L^p$ of bilinear pseudo-differential operators is proved under the assumption that their symbols are in the bilinear H\"ormander class $BS^m_{\rho,\rho}$,

Grand Triebel-Lizorkin-Morrey spaces

open access: yesDemonstratio Mathematica
This article studies the Triebel-Lizorkin-type spaces built on grand Morrey spaces on Euclidean spaces. We establish a number of characterizations on the grand Triebel-Lizorkin-Morrey spaces such as the Peetre maximal function characterizations, the ...

Riesz transform characterization of Hardy spaces associated with Schr\"odinger operators with compactly supported potentials

open access: yes, 2009
Let L=-\Delta+V be a Schr\"odinger operator on R^d, d\geq 3. We assume that V is a nonnegative, compactly supported potential that belongs to L^p(R^d), for some p>d/2. Let K_t be the semigroup generated by -L.
