Translativity of absolute weighted mean summability Cihan Orhan (1998) Czechoslovak Mathematical Journal In this paper, we give necessary and sufficient conditions on ( p n ) for | R , p n | k , k ≥ 1 , to be translative. So we extend the known results of Al-Madi [1] and Cesco 4 to the case k > 1 .
