Characterizations of weakly -analytic and Vašák spaces using projectional skeletons and separable PRI
Claudia Correa, Marek Cúth, Jacopo Somaglia
We find characterizations of Vašák spaces and weakly -analytic spaces using the notions of separable projectional resolution of the identity (SPRI) and of projectional…
Small semi-Eberlein compacta and inverse limits
Claudia Correa, Tommaso Russo, Jacopo Somaglia
We study properties of semi-Eberlein compacta related to inverse limits. We concentrate our investigation on an interesting subclass of small semi-Eberlein compacta whose elements…
Characterization of (semi-)Eberlein compacta using retractional skeletons
Claudia Correa, Marek Cúth, Jacopo Somaglia
We deeply study retractions associated to suitable models in compact spaces admitting a retractional skeleton and find several interesting consequences. Most importantly, we provid…
On the c_0-extension property
Claudia Correa
In this work we investigate the c_0-extension property. This property generalizes Sobczyk's theorem in the context of nonseparable Banach spaces. We prove that a sufficient conditi…
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…
