Fejer-Hadamard Inequlality for Convex Functions on the Coordinates in a Rectangle from the Plane

International Journal of Analysis and Applications, 2016
We give Fejer-Hadamard inequality for convex functions on coordinates in the rectangle from the plane. We define some mappings associated to it and discuss their properties.

Fejér–Hadamard Type Inequalities for (α, h-m)-p-Convex Functions via Extended Generalized Fractional Integrals

Fractal and Fractional, 2021
Integral operators of a fractional order containing the Mittag-Leffler function are important generalizations of classical Riemann–Liouville integrals. The inequalities that are extensively studied for fractional integral operators are the Hadamard type ...

Accelerating the alternating projection algorithm for the case of affine subspaces using supporting hyperplanes [PDF]

, 2014
The von Neumann-Halperin method of alternating projections converges strongly to the projection of a given point onto the intersection of finitely many closed affine subspaces.

Some New Hermite-Hadamard-Fejér Fractional Type Inequalities for h-Convex and Harmonically h-Convex Interval-Valued Functions

Mathematics, 2021
In this article, firstly, we establish a novel definition of weighted interval-valued fractional integrals of a function Υ˘ using an another function ϑ(ζ˙).

Interpolation and random interpolation in de Branges–Rovnyak spaces

Journal of the London Mathematical Society, Volume 112, Issue 4, October 2025.
Abstract The aim of this paper is to characterize universal and multiplier interpolating sequences for de Branges–Rovnyak spaces H(b)$\mathcal {H}(b)$ where the defining function b$b$ is a general non‐extreme rational function. Our results carry over to recently introduced higher order local Dirichlet spaces and thus generalize previously known results

Kutatások a diadikus harmonikus analízis körében = Research in dyadic harmonic analysis [PDF]

, 2009
A pályázat keretében írott cikkek között számosban foglalkoztam egy és kétváltozós integrálható függvények logaritmikus közepeinek konvergenciájával. Többek között vizsgáltuk, hogy mi a legbővebb norma konvergencia tér.

Local Whittle estimation in time‐varying long memory series

Journal of Time Series Analysis, Volume 46, Issue 4, Page 647-673, July 2025.
The memory parameter is usually assumed to be constant in traditional long memory time series. We relax this restriction by considering the memory a time‐varying function that depends on a finite number of parameters. A time‐varying Local Whittle estimator of these parameters, and hence of the memory function, is proposed.

Maximal Operators Associated With Walsh‐Paley Systems on Dyadic Hardy Spaces

Mathematical Methods in the Applied Sciences, Volume 48, Issue 9, Page 9770-9777, June 2025.
ABSTRACT The concept of a critical point of the maximum operator T$$ T $$ associated with the Walsh‐Paley system is the focus of this study. Namely, a point p0∈(0,1)$$ {p}_0\in \left(0,1\right) $$ is called critical with respect to T$$ T $$, if T$$ T $$ is bounded from Hp$$ {H}_p $$ to Lp$$ {L}_p $$, for all p>p0$$ p>{p}_0 $$ and it is not bounded from

Curves defined by a class of discrete operators: Approximation result and applications

Mathematical Methods in the Applied Sciences, Volume 48, Issue 2, Page 2388-2403, 30 January 2025.
In approximation theory, classical discrete operators, like generalized sampling, Szász‐Mirak'jan, Baskakov, and Bernstein operators, have been extensively studied for scalar functions. In this paper, we look at the approximation of curves by a class of discrete operators, and we exhibit graphical examples concerning several cases. The topic has useful
