| Aug 31, 2020 at 16:21 | comment | added | fedja | "such that every element $f\in B_{d,n}$ can be obtained by restricting $F$ to some suitable linear subspace" Just to clarify what exactly you mean by this. Is it that there exists a norm-preserving linear mapping $U:\mathbb R^n\to\mathbb R^N$ such that $f=F\circ U$, or is it something stronger? | |
