Luxemburg and Zaanen [5] call an element φ of the topological dual of a normed or seminormed vector space V an integral if
We denote the space of integrals by VI, For the Lλ function spaces introduced by Ellis and Halperin [2] another Banach subspace of the dual emerges, namely the conjugate space Lλ* which is the Lλ space determined by the conjugate length function λ*-Lλ* is contained in (Lλ)I but need not coincide with it.
