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) .

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 ...

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 $BS^m_{\rho,\rho}$,

On the L p-boundedness of Calderón-Zygmund operators

open access: yesAdvanced Nonlinear Studies
The main result in this paper is that, for singular integral operators associated with standard kernels, local L 1-estimates imply global L p-estimates for every p ∈ (1, ∞).

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.

The Neumann function and the L p Neumann problem in chord-arc domains

open access: yesAdvanced Nonlinear Studies
We construct the Neumann function in a 1-sided chord-arc domain (i.e., a uniform domain with an Ahlfors regular boundary), and establish size and Hölder continuity estimates up to the boundary.

On the restricted summability of the multi-dimensional Vilenkin-Cesàro means

open access: yes, 2017
The properties of the maximal operator of the (C,α) -means (α = (α1, . . . ,αd) ) of the multi-dimensional Vilenkin-Fourier series are discussed, where the set of indices is inside a cone-like set.
