On Pointwise Approximation of Conjugate Functions by Some Hump Matrix Means of Conjugate Fourier Series

摘要

The results generalizing some theorems onN, pnE, γsummability are shown. The same degrees of pointwise approximation as in earlier papers by weaker assumptions on considered functions and examined summability methods are obtained. From presented pointwise results, the estimation on norm approximation is derived. Some special cases as corollaries are also formulated.
