We prove that several definitions of integral multilinear mappings given in the literature are equivalent. We show that what we call S-factorizable multilinear mappings are integral, but that the converse is not true (contrary to earlier claims). Using S-factorizable polynomials we give characterizations of ${\mathscr L}_\infty$-spaces, Asplund spaces, spaces not containing $\ell_1$, and spaces with the compact range property. Some of these characterizations seem to be new even for linear operators.

Abstract

We prove that several definitions of integral multilinear mappings given in the literature are equivalent. We show that what we call S-factorizable multilinear mappings are integral, but that the converse is not true (contrary to earlier claims). Using S-factorizable polynomials we give characterizations of ${\mathscr L}_\infty$-spaces, Asplund spaces, spaces not containing $\ell_1$, and spaces with the compact range property. Some of these characterizations seem to be new even for linear operators.
