Abstract

We show that if we assume Martin's Axiom, then there exists a nontrivial twisted sum of c(0) and C(K) for every compact space K with finite height and weight at least continuum. This result settles the problem of existence of nontrivial twisted sums of c(0) and C(K) for finite height spaces K under Martin's Axiom. (AU)
