On the three space property for $C(K)$-spaces

Functional Analysis 2026-02-20 v1

Abstract

Assuming p=c\mathfrak p=\mathfrak c, we show that for every Eberlein compact space LL of weight c\mathfrak c there exists a short exact sequence 0c0XC(L)00\to c_0\to X\to C(L)\to 0, where the Banach space XX is not isomorphic to a C(K)C(K)-space.
