Kalton-Peck space is not isomorphic to its hyperplanes
A. Das, V. Ferenczi, Ch. Rosendal
Let denote the real Kalton-Peck space. No hyperplane of admits a complex structure, and is even in the sense of Ferenczi-Galego. Therefore, is not linearly…
Abstract embeddability ranks
Florent P. Baudier, Christian Rosendal
We describe several ordinal indices that are capable of detecting, according to various metric notions of faithfulness, the embeddability between pairs of Polish spaces. These embe…
On uniform and coarse rigidity of
Christian Rosendal
If is an almost transitive Banach space with amenable isometry group (for example, if with ) and admits a uniformly continuous map $X\ov…
Finite conjugacy classes and split exact cochain complexes
Christian Rosendal
We study the cohomology of isometric group actions on (super) reflexive Banach spaces with a focus on the relation between finite conjugacy classes and split exactness of cochain c…
Light groups of isomorphisms of Banach spaces and invariant LUR renormings
Leandro Antunes, Valentin Ferenczi, Sophie Grivaux +1
Megrelishvili defines \emph{light groups} of isomorphisms of a Banach space as the groups on which the Weak and Strong Operator Topologies coincide, and proves that every bounded g…
Lipschitz structure and minimal metrics on topological groups
Christian Rosendal
We discuss the problem of deciding when a metrisable topological group has a canonically defined local Lipschitz geometry. This naturally leads to the concept of minimal metric…
