Inequalities involving upper bounds for certain matrix operators

In this paper, we considered the problem of finding the upper bound Hausdorff matrix operator from sequence spaces l_p(v) (ord(v, p)) intol _p (w) (ord(w, p)). Also we considered the upper bound problem for matrix operators fromd(v, 1) intod(w, 1), and matrix operators frome(w, ∞) intoe(v, ∞), and deduce upper bound for Cesaro, Copson and Hilbert matrix operators, which are recently considered in [5] and [6] and similar to that in [10].
