Approximation of periodic analytic functions by Fejer sums
Journal Title: Математичні Студії - Year 2017, Vol 47, Issue 2
Abstract
For upper bounds of the deviations of Fejer sums taken over classes of periodic functions that admit analytic extensions to a fixed strip of the complex plane, we obtain asymptotic equalities. In certain cases, these equalities give a solution of the corresponding Kolmogorov-Nikolsky problem.

On bonding of some bitopological notions
In this paper, we study two strong forms of separations axioms on bitopological spaces and we observe that the results on such axioms are odd compared to prevailing results of bitopological spaces or topological spaces,...
An extremal problem for volume functionals
We consider the class of ring Q-homeomorphisms with respect to p-modulus in Rn with p>n, and obtain a lower bound for the volume of images of a ball under such mappings. In particular, the following theorem is proved in...
The interaction of the asymmetrical screw flows for the Bryan-Pidduck model
Some approximate solutions of the Boltzmann equation for a model of rough spheres are constructed. Several sufficient conditions which minimize the uniform-integral error between parts of the Bryan-Pidduck equation are o...
Weakly weighted-sharing and uniqueness of homogeneous differential polynomials
In the year 2006, S. Lin and W. Lin introduced the definition of weakly weighted-sharing of meromorphic functions which is between ``CM'' and ``IM''. In this paper, using the notion of weakly weighted-sharing, we study t...
Relative growth of Dirichlet series
Let F and G be entire functions given by Dirichlet series with exponents increasing to +∞. In the term of generalized order it is introduced a concept of their relative growth and its connection with the growth of F and...
