Similarity:

We show that the same degree of approximation as in the theorems proved by L. Leindler [Trigonometric approximation in $L^{p}$ -norm, J. Math. Anal. Appl. 302 (2005), 129–136] and P. Chandra [Trigonometric approximation of functions in $L^{p}$ -norm, J. Math. Anal. Appl. 275 (2002), 13–26] is valid for a more general class of lower triangular matrices. We also prove that these theorems are true under weakened assumptions.

Similarity:

In this paper we consider the problem of finding upper bounds of certain matrix operators such as Hausdorff, Nörlund matrix, weighted mean and summability on sequence spaces $l_{p} (w)$ and Lorentz sequence spaces $d (w, p)$ , which was recently considered in [9] and [10] and similarly to [14] by Josip Pecaric, Ivan Peric and Rajko Roki. Also, this study is an extension of some works by G. Bennett on $l_{p}$ spaces, see [1] and [2].
