$On moduli of smoothness of fractional order$

12 p, 201.3 KB

On moduli of smoothness of fractional order / Tikhonov, Sergey Yu. ; Centre de Recerca Matemàtica
In this paper we consider the properties of moduli of smoothness of fractional order. The main result of the paper describes the equivalence of the modulus of smoothness and a function from some class.

Embedding theorems of funcitional classes, III / Simonov, Boris V. ; Tikhonov, Sergey Yu. ; Centre de Recerca Matemàtica
In this paper we obtain the necessary and sufficient conditions for embedding results of different function classes. The main result is a criterion for embedding theorems for the so-called generalized Weyl-Nikol'skii class and the generalized Lipschitz class. [...]

Convolution inequalities in Lorentz spaces / Nursultanov, Erlan ; Tikhonov, Sergey Yu. ; Centre de Recerca Matemàtica
In this paper we study boundedness of the convolution operator in different Lorentz spaces. In particular, we obtain the limit case of the Young-O'Neil inequality in the classical Lorentz spaces. We also investigate the convolution operator in the weighted Lorentz spaces. [...]

Net spaces and boundedness of integral operators / Nursultanov, Erlan ; Tikhonov, Sergey Yu. ; Centre de Recerca Matemàtica
In this paper we introduce new functional spaces which we call the net spaces. Using their properties, the necessary and sufficient conditions for the integral operators to be of strong or weak-type are obtained. [...]

Norm inequalities in multidimensional Lorentz spaces / Simonov, Boris V. ; Tikhonov, Sergey Yu. ; Centre de Recerca Matemàtica
In this paper we obtain necessary and sufficient conditions for double trigonometric series to belong to generalized Lorentz spaces, not symmetric in general. Estimates for the norms are given in terms of coefficients.
