Diagonal extendible multilinear operators between ${\ell }_p$-spaces

Daniel Carando, Verónica Dimant, Pablo Sevilla-Peris +1

We study extendibility of diagonal multilinear operators from ${\ell }_p$ to ${\ell }_q$ spaces. We determine the values of $p$ and $q$ for which every diagonal $n$-linear operator is ex…
