Strong approximation of almost periodic functions
Strong approximation of almost periodic functions
We consider summability methods generated by the class GM ( 2 β ) .We generalize some related results of P. Pych-Taberska [Studia Math.XCVI (1990), 91-103] on strong approximation of almost periodic functions by their Fourier series and S. M. Mazhar and V.Totik [J.Approx.Theory, 60(1990), 174-182] on approximation of periodic functions …
