On the Riesz transforms for the inverse Gauss measure

open access: yesAnnales Fennici Mathematici, 2021
Let $γ_{-1}$ be the absolutely continuous measure on $\mathbb{R}^n$ whose density is the reciprocal of a Gaussian function. Let further $\mathscr{A}$ be the natural self-adjoint Laplacian on $L^2(γ_{-1})$. In this paper, we prove that the Riesz transforms associated with $\mathscr{A}$ of order one or two are of weak type $(1,1)$, but that those of ...

Regularity of Riesz Measures [PDF]

open access: yesProceedings of the American Mathematical Society, 1986
It is shown that Riesz measures are inner regular, i.e., each Borel set may be approximated from inside by closed sets, if the basic space is metacompact or para-Lindelöf. On the other hand, an example is given to show that local compactness is not sufficient to ensure inner regularity of Riesz measures.

Asymptotics of $\delta$-subharmonic functions of finite order

open access: yesМатематичні Студії, 2020
For $\delta$-subharmonic in $\mathbb{R}^m$, $m\geq2$, function $u=u_1-u_2$ of finite positive order we found the asymptotical representation of the form \[ u(x)=-I(x,u_1)+I(x,u_2) +O\left(V(|x|)\right),\ x\to\infty, \] where $I(x,u_i)=\int\limits_{|a-x ...

Riesz transforms on the Hardy space associated with generalized Schrödinger operators

open access: yesJournal of Inequalities and Applications, 2019
Let L=−Δ+μ $\mathcal{L}=-\Delta +\mu $ be a generalized Schrödinger operator, where the measure μ is a nonnegative Radon measure. In this paper, we establish the molecular characterization of the Hardy type space HL1(Rn) $H^{1}_{\mathcal{L}}(\mathbb{R ...

ON ENTIRE FUNCTIONS WITH GIVEN ASYMPTOTIC BEHAVIOR

open access: yesПроблемы анализа, 2018
We study approximation of subharmonic functions on the complex plane by logarithms of moduli of entire functions. In the theory of series of exponentials these entire functions are the main tool.

A New Approach to Continuous Riesz Bases [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 2013
This paper deals with continuous frames and continuous Riesz bases. We introduce continuous Riesz bases and give some equivalent conditions for a continuous frame to be a continuous Riesz basis.

A study on Matrix Domain of Riesz-Euler Totient Matrix in the Space of $p$-Absolutely Summable Sequences

open access: yesCommunications in Advanced Mathematical Sciences, 2021
In this study, a special lower triangular matrix derived by combining Riesz matrix and Euler totient matrix is used to construct new Banach spaces. $\alpha-$,$\beta-$,$\gamma-$duals of the resulting spaces are obtained and some matrix operators ...

A trace problem for associate Morrey potentials

open access: yesAdvances in Nonlinear Analysis, 2018
As a solution to the restriction question for associate Morrey potentials (Question 1.1), this paper characterizes a Radon measure μ on ℝn{\mathbb{R}^{n}} such that the Riesz operator Iα{I_{\alpha}} maps the associate Morrey spaces H1p,κ⊂Hp,κ{H^{p,\kappa}
