On double absolute factorable matrix summabilityV.N. Mishra, S.K. Paikray, P. Palo, P.N. Samanta, M. Misra, U.K. MisraIn this article a new result on |A, pm, qn; δ|k summability of doubly infinite lower triangular matrix has been establised which generalizes a theorem of E. Savas and B.E. Rhoades and subsequently a theorem of Paikray et al. on summability factor of double infinite weighted mean matrix.Tbilisi Mathematical Journal, Vol. 10(4) (2017), pp. 29-44 |
