Necessary and sufficient conditions for the boundedness of the anisotropic Riesz potential in anisotropic modified Morrey spaces

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2013
We prove that the anisotropic fractional maximal operator Mα,σ and the anisotropic Riesz potential operator Iα,σ, 0 < α < ∣σ∣ are bounded from the anisotropic modified Morrey space L̃1,b,σ(Rn) to the weak anisotropic modified Morrey space WL̃q,b,σ(Rn) if

Financial Statement Information and Equity Value: The Role of Real Options Characteristics

Financial Management, Volume 55, Issue 2, Page 301-328, Summer 2026.
ABSTRACT This paper examines whether firm‐specific real options characteristics are equity value‐relevant beyond valuation estimates anchored in financial statements. Using extensive historical data for the United Kingdom, we assess and compare the forecast accuracy and explanatory power for stock prices of equity valuation models based on residual ...

Riesz potential operators and inverses via fractional centred derivatives

International Journal of Mathematics and Mathematical Sciences, 2006
Fractional centred differences and derivatives definitions are proposed, generalizing to real orders the existing ones valid for even and odd positive integer orders. For each one, suitable integral formulations are obtained.

Hub‐and‐Spoke Collusion With a Third‐Party Pricing Algorithm

The Journal of Industrial Economics, Volume 74, Issue 2, Page 181-196, June 2026.
ABSTRACT A data analytics company delivers an efficiency by supplying a pricing algorithm that allows prices to more effectively respond to demand variation. In this setting, I consider a new form of hub‐and‐spoke collusion: A data analytics company (hub) coordinates the prices of competitors (spokes) through its pricing algorithm.

A Characterization of Riesz Potential and Its Commutator in Local Complementary Generalized Orlicz–Morrey Spaces

Journal of Function Spaces
In this paper, we find sufficient conditions on functions ω1,ω2 which ensure the boundedness of Riesz potentials and their commutators with BMO functions from one local complementary generalized Orlicz–Morrey spaces M ∁Φ,ω1x0ℝn to the spaces M ∁Ψ,ω2x0ℝn.

Spatial depth for data in metric spaces

Scandinavian Journal of Statistics, Volume 53, Issue 2, Page 684-711, June 2026.
Abstract We propose a novel measure of statistical depth, the metric spatial depth, for data residing in an arbitrary metric space. The measure assigns high (low) values for points located near (far away from) the bulk of the data distribution, allowing quantifying their centrality/outlyingness.

Riesz potentials, higher Riesz transforms and Beppo Levi spaces

Hiroshima Mathematical Journal, 1988
The main center of investigations in this paper originates from the representation of the solution of the equation \[ \Delta^ \ell u=f, \quad \ell=1,2,\dots,\text{ with } f\in L_ p(\mathbb{R}^ n), \quad p>1.\tag{1} \] It is connected with the representation of functions from the space \({\mathcal L}_ m^ p=\{u\in{\mathcal D}'\): \(D^ \alpha u\in L_ p\),

A strong quantitative form of the fractional isoperimetric inequality

Journal of the London Mathematical Society, Volume 113, Issue 6, June 2026.
Abstract We show a strong version of the fractional quantitative isoperimetric inequality, in which the isoperimetric deficit controls not only the Fraenkel asymmetry but also a sort of oscillation of the boundary. This generalizes the local result by Fusco and Julin in [22].

Hardy-Littlewood-Sobolev Inequalities on p-Adic Central Morrey Spaces

Journal of Function Spaces, 2015
We establish the Hardy-Littlewood-Sobolev inequalities on p-adic central Morrey spaces. Furthermore, we obtain the λ-central BMO estimates for commutators of p-adic Riesz potential on p-adic central Morrey spaces.
