We generalize and improve in some cases the results of Mahapatra and Chandra [7]. As a measure of Hölder norm approximation, generalized modulus-type functions are used.

On the approximation of function by Robel matrix

On the approximation of functions by matrix means in the generalized Hölder metric

Włodzimierz Łenski, Bogdan Szal (2008)

Banach Center Publications

Under some assumptions on the matrix of a summability method, whose rows are sequences of bounded variation, we obtain a generalization and an improvement of some results of Xie-Hua Sun and L. Leindler.

On the degree of strong approximation of integrable functions in Stepanov sense

Włodzimierz Łenski, Bogdan Szal (2014)

Banach Center Publications

Considering the class of almost periodic functions integrable in the Stepanov sense we extend and generalize certain results of the first author, as well as of L. Leindler and P. Chandra.

On the Hausdorff summability of series associated with a Fourier and its allied series

B. L. Gupta (1971)

Annales de l'institut Fourier

Recently, Tripathy - Jour. Ind. Math. Soc., 32 (1960), 141-154 - has proved some results on absolute Hausdorff summability of some series associated with Fourier series and its allied series, which generalise the results proved by Mohanty on absolute Cesaro summability. Proceeding on the similar lines, the author has generalised the results of Cheng - Duke Math. Jour., 15 (1948), 17-27 - by proving them on absolute Hausdorff summability.
