VL - 5 IS - SE - Articles DO - 10.15377/2409-5761.2018.05.1 UR - https://www.avantipublishers.com/index.php/jaacm/article/view/841 SP - 1-11 AB - <p>In the present paper an overview of existing results on matrix transforms of summability and absolute summability domains of matrix methods by factorable matrices is presented. Under the notion “multiplicative matrix” we consider a lower triangular matrix <em>M </em>= (<em>m</em><em><sub>nk</sub></em>), where <em>m</em><em><sub>nk</sub></em> = <em>r</em><em><sub>n</sub></em><em>v</em><em><sub>k</sub></em> with <em>r</em><em><sub>n</sub></em><em>,</em><em>v</em><em><sub>k</sub></em> <em>ϵ </em><em>C</em>.</p> ER -
