Pointwise strong approximation of almost periodic functions in S^1
Wlodzimierz Lenski, Bogdan Szal
We consider the class GM(2b) in pointwise estimate of the deviations in strong mean of S^1 almost periodic functions from matrix means of partial sums of their Fourier series.
On the degree of strong approximation of almost periodic functions in the Stepanov sense
Wlodzimierz Lenski, Bogdan Szal
Considering the class of almost periodic functions in the Stepanov sense we extend and generalize the results of the first author [4]. as well as the results of L. Leindler [3] and…
On trigonometric approximation of functions in the Lp norm
R. N. Mohapatra, B. Szal
In this paper we obtain degree of approximation of functions in Lp by operators associated with their Fourier series using integral modulus of continuity. These results generalize…
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.
On some Leindler's theorem on application of the class NMCS
Włodzimierz Łenski, Bogdan Szal
We show the results in the class GM(5b) corresponding to the theorem of L. Leindler [A note on strong approximation of Fourier series, Analysis Mathematica, 29(2003), 195--199] on…
Strong approximation of almost periodic functions
Włodzimierz Łenski, Bogdan Szal
We consider summability methods generated by the class GM(2b). We generalize some related results of P. Pych-Taberska [Studia Math. XCVI (1990), 91-103] on strong approximation of…
