Global second‐order estimates in anisotropic elliptic problems

Proceedings of the London Mathematical Society, Volume 130, Issue 3, March 2025.
Abstract This work deals with boundary value problems for second‐order nonlinear elliptic equations in divergence form, which emerge as Euler–Lagrange equations of integral functionals of the Calculus of Variations built upon possibly anisotropic norms of the gradient of trial functions.

Continuity of multilinear operators on Triebel-Lizorkin spaces

Journal of Inequalities and Applications, 2006
The continuity of some multilinear operators related to certain convolution operators on the Triebel-Lizorkin space is obtained. The operators include Littlewood-Paley operator and Marcinkiewicz operator.

Generosity of old‐age pensions for the self‐employed—A typology of European welfare states

International Journal of Social Welfare, Volume 34, Issue 1, January 2025.
Abstract Research on pension generosity has so far used employees in standard employment as the reference point, ignoring nonstandard forms of employment such as the self‐employed. Moreover, as one of the major concepts of welfare state analysis, generosity has not been considered in research on the old‐age security of the self‐employed.

Sharp function estimates and boundedness for Toeplitz-type operators associated with general fractional integral operators

Open Mathematics, 2021
In this paper, we establish some sharp maximal function estimates for certain Toeplitz-type operators associated with some fractional integral operators with general kernel.

Marcinkiewicz–Zygmund inequalities in variable Lebesgue spaces

Banach Journal of Mathematical Analysis
We study $\ell^r$-valued extensions of linear operators defined on Lebesgue spaces with variable exponent. Under some natural (and usual) conditions on the exponents, we characterize $1\leq r\leq \infty$ such that every bounded linear operator $T\colon L^{q(\cdot)}(Ω_2, μ)\to L^{p(\cdot)}(Ω_1, ν)$ has a bounded $\ell^r$-valued extension.

Impact of information shortcuts on preferential voting: Gender and ballot position effects in Luxembourg and Switzerland

Swiss Political Science Review, Volume 30, Issue 4, Page 446-471, December 2024.
Abstract Free party lists provide voters with greater freedom of choice than other electoral systems, allowing them to select candidates within and between parties. Given that free party lists are cognitively highly demanding, voters have incentives to use shortcuts to discriminate between candidates. This study uses multilevel linear regression models

Real interpolation for non-distant marcinkiewicz spaces

Revista Matemática Complutense, 2001
Lorentz-Zygmund spaces \(L^{p,r}(\log L)^\alpha\), introduced by \textit{C. Bennett} and \textit{K. Rudnick} in [Diss. Math. 175, 67 p. (1980; Zbl 0456.46028)], were generalized to new spaces \(L_{p,\alpha,E}\) on \((0,1)\) by the author in [J. Anal. Math.

Commutators for Approximation Spaces and Marcinkiewicz-Type Multipliers

Journal of Approximation Theory, 1999
Taking into account that the description of approximation spaces and the calculation of almost optimal approximation elements, in combination with real interpolation, are very useful in the commutation theorems, the author shows, in this paper, under some conditions weaker than those of Marcinkievicz multiplier theorem, that the multiplier operator ...

Who Runs for Higher Office? Electoral Institutions and Level‐Hopping Attempts in Germany's State Legislatures

Legislative Studies Quarterly, Volume 49, Issue 3, Page 481-549, August 2024.
Do electoral institutions matter for subnational legislators’ career choices in a multi‐level polity? The paper considers this question by analyzing candidacies of sitting German State MPs for the Federal parliament (“level‐hopping attempts”), leveraging cross‐ and within‐legislature variation in electoral rules (due to the widespread adoption of mixed‐

Reduction procedure for obtaining solutions of the scalar additive Jump problem and Riemann boundary value problem in vectorial Clifford analysis

Mathematical Methods in the Applied Sciences, Volume 47, Issue 11, Page 8611-8625, 30 July 2024.
In this paper, we study existence of solutions to the scalar additive Jump problem and the Riemann boundary value problems in the context of vectorial Clifford analysis on domains with fractal boundaries. A reduction procedure is applied with great effectiveness to find the solution of the problems.
