Resumo:
A Dunford–Pettis operator is a linear operator that maps weakly convergent sequences into norm-convergent sequences. This work investigates the properties of positive operators defined on Banach lattices, with an emphasis on domination results. Specifically, we analyze the behavior of operators S and T satisfying 0 ≤ S ≤ T, seeking to determine how the properties of the dominating operator T, such as compactness or being a Dunford–Pettis operator, influence the operator S and its powers.
