Raimi, Invariant means and invariant matrix methods of summability, Duke Math. J. 30 (1963) 81-94] and [S.L. Mishra, B. Satapathy, N. Rath, Invariant means and σ-core, J. Indian Math. Soc. 60 (1984) 151-158], respectively. In this work, we extend these ideas to double sequences.  ISSN : 0893-9659  Journal Name : Applied Mathematics Letters  Volume : 19  Issue Number : 10  Publishing Year : 1427 AH 2006 AD  Article Type : Article  Added Date : Tuesday, December 27, 2011  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email Celal Çakan Çakan, Celal Researcher Doctorate ccakan@inonu.edu.tr Bilal Altay Altay, Bilal Researcher Doctorate ccakan@inonu.edu.tr محمد مرسلين Mursaleen, Mohammad Researcher Doctorate mursaleenm@gmail.com Files File Name Type Description  31800.pdf pdf Abstract Back To Researches Page
