Summary:  As a consequence of the analysis of the class of $(p,q)$-power concave operators, we prove a general representation theorem for $p$-convex and $q$-concave Banach lattices as spaces of integrable functions with respect to vector measures. This result culminates a series of representation theorems for Banach lattices using vector measures that have been obtained in the last twenty years.
