Abstract

In this paper, we considered the problem of finding the upper bound Hausdorff matrix operator from sequence spaces l_p(v) (or d(v,p)) into l_p(w) (or d(w,p)). Also we considered the upper bound problem for matrix operators from d(v,1) into d(w,1), and matrix operators from e(w,∞) into e(v,∞), and deduce upper bound for Cesaro, Copson and Hilbert matrix operators, which are recently considered in \cite5 and \cite6 and similar to that in \cite10.
