Pointwise (H, Φ) Strong Approximation by Fourier Series of LΨ Integrable Functions
Pointwise (H, Φ) Strong Approximation by Fourier Series of LΨ Integrable Functions
We essentially extend and improve the classical result of G. H. Hardy and J. E. Littlewood on strong summability of Fourier series. We will present an estimation of the generalized strong mean (H, Φ) as an approximation version of the Totik type generaliza- tion of the result of G. H. …
