In this work we consider all bounded linear operators T on lp(I), where I is a nonempty set and p ∈ [1,+∞), which preserve a preorder on lp(I), which is called "convex majorization". The interested properties of these operators are investigated. We also obtain some characterization theorems and prove an important property of them, that is, the row sums of matrix form of such an operator lies in the bounded closed interval of R.
