Geometric duality, perfect graphs, and the SierpiÅski space
Piotr Borodulin-Nadzieja, Barnabás Farkas, Anna Pelczar-Barwacz
In their classical paper \emph{On the stopping time Banach space}, Bang and Odell, among a plethora of results concerning the dyadic stopping time space and its dual, presented the…
Banach spaces with arbitrary finite Baire order
Anna Pelczar-Barwacz, ZdenÄk Silber, Tomasz Wawrzycki
We investigate intrinsic Baire classes of Banach spaces defined by Argyros, Godefroy and Rosenthal (2003). We introduce a construction, for any Banach space with a basis, of an…
On the spaces dual to combinatorial Banach spaces
Piotr Borodulin-Nadzieja, Sebastian Jachimek, Anna Pelczar-Barwacz
We present quasi-Banach spaces which are closely related to the duals of combinatorial Banach spaces. More precisely, for a compact family of finite subsets of w…
A Banach space with an infinite dimensional reflexive quotient algebra L(X)/SS(X)
Anna Pelczar-Barwacz
We construct a Banach space X of Gowers-Maurey type such that the algebra of bounded operators L(X) is a direct sum of an infinite dimensional reflexive Banach space and the operat…
