On Conservative Matrices in Summability of Series

Abstract

In the present paper, we give some sufficient conditions for a matrix belongs to the class $B\left( \alpha_{n},\beta_{n};\gamma_{n},\delta_{n};\varphi\right) $ when $\varphi\in\Delta\left( p,q\right) .$ Our results generalize the result of Das [4] and Yu [9]. Some applications of the main results are given.
