Abstract
If T is an isomorphism of (c0) into C(Ω) (where Ω is a sequentially compact and paracompact space, or a compact metric space in particular), which satisfies the condition ||T||⋅||T-1||≤1+ɛ for some ɛ∈ (0, ⅕), then is close to an isometry with an error less than 9 ɛ. The proof of this article is simple without using the dual space or adjoint operator.
