Pointwise strong approximation of almost periodic functions
Radosława Kranz, Włodzimierz Łenski, Bogdan Szal
We consider the class GM(2b) in pointwise estimate of the deviations in strong mean of almost periodic functions from matrix means of partial sums of their Fourier series.

Approximation of functions from Lp(w)b by matrix means of their Fourier series
Radosława Kranz, Włodzimierz Łenski, Bogdan Szal
We formulate some special conditions for the integrable functions and moduli of continuity. We give the results on rate of approximation of such functions by matrix means of their…
