On Fractional Smoothness of Modulus of Functions
Annals of Applied Mathematics, 2021 We consider the Nemytskii operators $u\to |u|$ and $u\to u^{\pm}$ in a bounded domain $\Omega$ with $C^2$ boundary.

Smooth blowup square for motives with modulus
Bulletin of the Polish Academy of Sciences Mathematics, 2021 In this self-contained paper we prove that Voevodsky's smooth blowup triangle of motives generalises to a smooth blowup triangle of motives with modulus.

Generalized Modulus of Smoothness in Banach Spaces
Journal of Harbin University of Science and Technology, 2018 In order to study the geometric constants of Banach space，a new method is extended to study new constants by means of extending the modulus of smoothness to the generalized smooth mode.

A modulus of smoothness for some Banach function spaces
Ukrains’kyi Matematychnyi Zhurnal, 2023 UDC 517.5 Based on the Steklov operator, we consider a modulus of smoothness of functions in some Banach function spaces, which can be not translation invariant and establish its main properties. A constructive characterization of the Lipschitz class is obtained by using the Jackson-type direct theorem and inverse theorem of trigonometric ...

Generalized Jacobian Weighted Modulus of Smoothness
Iraqi Journal of Science, 2023 The topic of modulus of smoothness still gets the interest of many researchers due to its applicable usage in different fields, especially for function approximation. In this paper, we define a new modulus of smoothness of weighted type. The properties of our modulus are studied.

Some Moduli of Angles in Banach Spaces
Mathematics, 2022 In this paper, we mainly discuss the angle modulus of convexity δXa(ϵ) and the angle modulus of smoothness ρXa(ϵ) in a real normed linear space X, which are closely related to the classical modulus of convexity δX(ϵ) and the modulus of smoothness ρX(ϵ ...
