Non-commutative Barge-Ghys quasimorphisms: an erratum
Michael Brandenbursky, Misha Verbitsky
This is an erratum to the paper ``Non-commutative Barge-Ghys quasimorphisms''. The effective version of Ambrose-Singer theorem used in this paper was mis-stated, making Theorem 3.1…
On quasimorphisms and distortion in homeomorphism groups
Michael Brandenbursky, Jarek Kedra, Michal Marcinkowski +1
Let be a smooth compact oriented connected manifold, and the group of homeomorphisms of supported away from which preserve a Borel proba…
The -diameter of the space of contractible loops
Michael Brandenbursky, Egor Shelukhin
We prove that the space of contractible simple loops of a given fixed area in any compact oriented surface has infinite diameter as a homogeneous space of the group of area-preserv…
Bounded cohomology of measure-preserving homeomorphism groups of non-orientable surfaces
Michael Brandenbursky, Lior Menashe
Let be a closed non-orientable surface of genus . Let be the identity component of the group of measure-preserving homeomorphisms of $N…
