A topological version of the Bergman property
Christian Rosendal
A topological group G is defined to have property (OB) if any G-action by isometries on a metric space, which is separately continuous, has bounded orbits. We study this topologica…
Turbulence, amalgamation and generic automorphisms of homogeneous structures
Alexander S. Kechris, Christian Rosendal
We study topological properties of conjugacy classes in Polish groups, with emphasis on automorphism groups of homogeneous countable structures. We first consider the existence of…
Incomparable, non isomorphic and minimal Banach spaces
Christian Rosendal
A Banach space contains either a minimal subspace or a continuum of incomparable subspaces. General structure results for analytic equivalence relations are applied in the context…
On a question of Haskell P. Rosenthal
Valentin Ferenczi, Anna Maria Pelczar, Christian Rosendal
We consider a normalized basis in a Banach space with the following property: any normalized block sequence of the basis has a subsequence equivalent to the basis. We show that und…
