In a previous paper [9], some classes of triangular matrix transformations between the series spaces summable by absolute weighted summability methods were characterized. present paper, we extend these to four dimensional matrices and double methods.

Quite recently, Bor (2021) [22] has proved two main theorems dealing with absolute Riesz summability factors of infinite series and Fourier by using an almost increasing sequence. In this paper, we have generalized these to the | A , p n k method.
