NettetThis answer doesn't prove anything, because its second paragraph is just a restatement of the question without any proof. Consider the function f ≡ 1 on L ∞ ( R, μ), then ‖ s − f ‖ ∞ > ε for any simple function s. In particular we can have ‖ s − f ‖ ∞ > 1. So simple functions may not be dense in L ∞. Nettet4. jul. 2012 · In this paper by Amir Bahman Nasseri, Gideon Schechtman, Tomasz Tkocz, and me it is shown that there is an injective, dense range, non surjective operator on $\ell_\infty$.The proof is not technically difficult but has some interest. From the theory of Tauberian operators one deduces that such an operator exists if and only if there is a …
