A New Variation on Absolute Summability

Yıl 2021, Cilt: 3 Sayı: 1, 1 - 9, 15.06.2021

In [4], Bor has proved a main theorem dealing with absolute weighted arithmetic mean summability factors of infinite series by using a positive non-decreasing sequence. In this paper, we have extended this result to absolute matrix summability method by using an almost increasing sequence in place of a positive non-decreasing sequence. Also, some new and known results are also obtained.
