| Abstract: | A lower triangular matrix with nonzero principal diagonal entries is called a triangle. In this paper we obtain the sufficient conditions for ∑anλn to be summable ∣A∣k whenever ∑an is summable ∣T∣k for a triangle T. |
| Keywords: | Abel summability Absolute summability Triangular matrices Summability factor Weighted mean matrix |
