摘要
We provide coincidence results for vector-valued ideals of multilinear operators. More precisely, if U is an ideal of n-linear mappings we give conditions for which the equality U(E-1, . . . , E-n; F) = U-min(E-1, . . . , E-n ; F) holds isometrically. As an application, we obtain in many cases that the monomials form a Schauder basis of the space U(E-1, . . . , E-n; F). Several structural and geometric properties are also derived using this equality. We apply our results to the particular case where U is the classical ideal of extendible or Pietsch-integral multilinear operators. Similar statements are given for ideals of vector-valued homogeneous polynomials. (c) 2014 Elsevier Inc. All rights reserved.
