A continuous image of a Radon-Nikodým compact which is not Radon-Nikodým
Antonio Avilés, Piotr Koszmider
We construct a continuous image of a Radon-Nikodým compact space which is not Radon-Nikodým compact, solving the problem posed in the 80ties by Isaac Namioka.
A C(K) Banach space which does not have the Schroeder-Bernstein property
Piotr Koszmider
We construct a totally disconnected compact Hausdorff space N which has clopen subsets M included in L included in N such that N is homeomorphic to M and hence C(N) is isometric as…
On large indecomposable Banach spaces
Piotr Koszmider
Hereditarily indecomposable Banach spaces may have density at most continuum (Plichko-Yost, Argyros-Tolias). In this paper we show that this cannot be proved for indecomposable Ban…
On universal spaces for the class of Banach spaces whose dual balls are uniform Eberlein compacts
Christina Brech, Piotr Koszmider
For k being the first uncountable cardinal w_1 or k being the cardinality of the continuum c, we prove that it is consistent that there is no Banach space of density k in which it…
