Approximation properties of hexagonal Fourier series in the generalized Hölder metric
(Heldermann Verlag, 2013)The generalized Holder classes of -periodic continuous functions are defined, and the approximation properties of CesA ro and Abel-Poisson means of hexagonal Fourier series of such functions are investigated in the Holder metric. -
Polynomial approximation of functions in weighted Lebesgue and Smirnov spaces with nonstandard growth
(Heldermann Verlag, 2011)This work deals with basic approximation problems such as direct, inverse and simultaneous theorems of trigonometric approximation of functions of weighted Lebesgue spaces with a variable exponent on weights satisfying a ...
