Regularizability of ill-posed problems and the modulus of continuity

, 2011
The regularization of linear ill-posed problems is based on their conditional well-posedness when restricting the problem to certain classes of solutions.

On the Generalized Baskakov Durrmeyer Operators

Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2019
The main object of this paper is to construct Baskakov Durrmeyer type operators such that their construction depends on a function ρ. Using the weighted modulus of continuity, we show the uniform convergence of the operators. Moreover we obtain pointwise

Szász-Durrmeyer operators involving Boas-Buck polynomials of blending type

Journal of Inequalities and Applications, 2017
The present paper introduces the Szász-Durrmeyer type operators based on Boas-Buck type polynomials which include Brenke type polynomials, Sheffer polynomials and Appell polynomials considered by Sucu et al. (Abstr. Appl. Anal. 2012:680340, 2012).

Kolmogorov inequalities for norms of Marchaud-type fractional derivatives of multivariate functions

Researches in Mathematics, 2020
We obtain new sharp Kolmogorov type inequalities, estimating the norm of mixed Marchaud type derivative of multivariate function through the C-norm of function itself and its norms in Hölder spaces.

On L2 modulus of continuity of Brownian local times and Riesz potentials [PDF]

, 2015
International audienceThis article is concerned with modulus of continuity of Brownian local times. Specifically, we focus on 3 closely related problems: (a) Limit theorem for a Brownian modulus of continuity involving Riesz potentials, where the limit ...

Functions of Bounded kth p-Variation and Continuity Modulus

Journal of Function Spaces, 2015
A scale of spaces exists connecting the class of functions of bounded kth p-variation in the sense of Riesz-Merentes with the Sobolev space of functions with p-integrable kth derivative.

On functions of van der Waerden type [PDF]

Известия Саратовского университета. Новая серия: Математика. Механика. Информатика, 2023
Let $\omega(t)$ be an arbitrary modulus of continuity type function, such that $\omega(t)/t\to+\infty$, as $t\to+0$. We construct a continuous nowhere-differentiable function $V_\omega(x)$, $x\in[0;1]$, that satisfies the following conditions: 1)  ...

A note on the modulus of continuity of a periodic function

Applied Mathematics Letters, 2011
AbstractLet f(x) be a periodic function with period T. In Rivlin (1969) [1] it is claimed that the modulus of continuity is independent of a on [a,a+T]. In this note we show that this is not correct.

Approximation properties of generalized Baskakov–Schurer–Szasz–Stancu operators preserving e−2ax,a>0 $e^{-2ax}, a>0$

Journal of Inequalities and Applications, 2019
The current paper deals with a modified form of the Baskakov–Schurer–Szasz–Stancu operators which preserve e−2ax $e^{-2ax}$ for a>0 $a>0$. The uniform convergence of the modified operators is shown.
