Nontrivial twisted sums for finite height spaces under Martin's Axiom
Claudia Correa
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. Th…

Additional set-theoretic assumptions and twisted sums of Banach spaces
Claudia Correa
In this paper, we discuss the role played by additional set-theoretic assumptions in the investigation of the existence of nontrivial twisted sums of and spaces of continuous…
