| Jun 6, 2022 at 3:12 | comment | added | Yemon Choi | The votes to close may have come because of ambiguity in the notation: by L($\ell^2$) do you mean all linear maps from $\ell^2\to \ell^2$, or just the bounded ones? In the latter case, your question has an immediate positive answer, so I assume you meant to merely assume D is well-defined as a linear map (in which case Danil Skurudin's argument suffices) | |
