Candido, Leandro; Galego, Elói Medina How far is \(C(\omega)\) from the other \(C(K)\) spaces? (English) Zbl 1288.46013 Stud. Math. 217, No. 2, 123-138 (2013). Summary: Denote by \(C(\alpha )\) the classical Banach space \(C(K)\) where \(K\) is the interval of ordinals \( [1, \alpha ]\) endowed with the order topology. In the present paper, we give an answer to a question posed in 1960 by C. Bessaga and A. Pełczyński [Stud. Math. 19, 53–62 (1960; Zbl 0094.30303)] by providing tight bounds for the Banach-Mazur distance between \(C(\omega )\) and any other \(C(K)\) space which is isomorphic to it. More precisely, we obtain lower bounds \(L(n, k)\) and upper bounds \(U(n, k)\) on \(d(C(\omega ), C(\omega ^{n} k))\) such that \(U(n,k)-L(n, k)<2\) for all \(1 \leq n, k <\omega \).
