Uniform Modulus of Continuity of Random Fields [PDF]

Monatshefte für Mathematik, 2009
A sufficient condition for the uniform modulus of continuity of a random field $X = \{X(t), t \in \R^N\}$ is provided. The result is applicable to random fields with heavy-tailed distribution such as stable random fields.

Functions with a concave modulus of continuity [PDF]

Proceedings of the American Mathematical Society, 1974
In [1], C. Goffman proved that, if σ \sigma is a modulus of continuity, then the set of all functions f in C [ 0 , 1 ] C[0,1] such that m ( { x : f ( x ) = g ( x ) } )

Approximate properties of Abel-Poisson integrals on classes of differentiable functions defined by moduli of continuity

Karpatsʹkì Matematičnì Publìkacìï, 2023
The paper deals with the problem of approximation in the uniform metric of $W^{1}H_{\omega}$ classes using one of the classical linear summation methods for Fourier series given by a set of functions of a natural argument, namely, using the Abel-Poisson ...

Functions of Bounded kth p-Variation and Continuity Modulus [PDF]

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.

Modulus of continuity of Kerov transition measure for continual Young diagrams [PDF]

Electronic Journal of Probability
The transition measure is a foundational concept introduced by Sergey Kerov to represent the shape of a Young diagram as a centered probability measure on the real line. Over a period of decades the transition measure turned out to be an invaluable tool for many problems of the asymptotic representation theory of the symmetric groups. Kerov also showed

Boundary modulus of continuity and quasiconformal mappings

Annales Academiae Scientiarum Fennicae Mathematica, 2012
In [the reviewer and \textit{R. Näkki}, J. Lond. Math. Soc., II. Ser. 44, No. 2, 339--350 (1991; Zbl 0755.30026)] it was shown that if in a bounded domain \(D\) a quasiconformal mapping \(f:D \rightarrow \mathbb{R}^n\), continuous in \(\overline{D}\), satisfies \[ |f(x) - f(y)| \leq M|x-y|^{\alpha}\quad\text{for all}\quad x,y \in \partial D, \] then \[

Two sharp inequalities for operators in a Hilbert space

Researches in Mathematics, 2022
In this paper we obtained generalisations of the L. V. Taikov’s and N. Ainulloev’s sharp inequalities, which estimate a norm of function's first-order derivative (L. V. Taikov) and a norm of function's second-order derivative (N.

Coefficients of multiple Fourier-Haar series and variational modulus of continuity

Қарағанды университетінің хабаршысы. Математика сериясы, 2023
In this paper, we introduce the concept of a variational modulus of continuity for functions of several variables, give an estimate for the sum of the coefficients of a multiple Fourier-Haar series in terms of the variational modulus of continuity, and ...
