Approximation of integrable functions by general linear matrix operators of their Fourier series
The pointwise estimates of the deviation Tn,Af(⋅)−f(⋅){T}_{n,A}f(\cdot )-f\left(\cdot ) in terms of pointwise moduli of continuity based on the points of differentiability of indefinite integral of ff, with application of the rth differences of the entries of AA, are proved. The similar results in c...
