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.

Ural Mathematical Journal, 2023 Some inequalities between the best simultaneous approximation of functions and their intermediate derivatives, and the modulus of continuity in a weighted Bergman space are obtained. When the weight function is \(\gamma(\rho)=\rho^\alpha,\) \(\alpha>0\),

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.

Application of the Modulus of Continuity in Characterizing Geodesics
پژوهشهای ریاضی, 2020 Introduction This paper concerns an application of the modulus of continuity in characterizing geodesics. The modulus of continuity of a continuous function between metric spaces is a two variable function which assigns to each point and to each positive

Approximation properties of generalized Baskakov operators
AIMS Mathematics, 2021 The present article is a continuation of the work done by Aral and Erbay [1]. We discuss the rate of convergence of the generalized Baskakov operators considered in the above paper with the aid of the second order modulus of continuity and the unified ...

Modulus of continuity estimates for fully nonlinear parabolic equations [PDF]
Calculus of Variations and Partial Differential Equations, 2021 We prove that the moduli of continuity of viscosity solutions to fully nonlinear parabolic partial differential equations are viscosity subsolutions of suitable parabolic equations of one space variable. As applications, we obtain sharp Lipschitz bounds and gradient estimates for fully nonlinear parabolic equations with bounded initial data, via ...
