such as Hausdorff, Nörlund matrix, weighted mean and summability on sequence spaces lp
(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 lp spaces, see [1] and [2].
