On quasimorphisms and distortion in homeomorphism groups

Michael Brandenbursky, Jarek Kedra, Michal Marcinkowski +1

Let $M$ be a smooth compact oriented connected manifold, and $Homeo_{0} (M, I^¼)$ the group of homeomorphisms of $M$ supported away from $\partial M,$ which preserve a Borel proba…

Sampling elements of a finite group: efficiency of the product replacement algorithm with an accumulator

MichaÅ Marcinkowski, Piotr Mizerka

Let $G$ be a finite group generated by $k$ elements. The well-known product replacement algorithm provides an effective method for sampling generating sets of $G$ . We study a refin…

Volume and Euler classes in bounded cohomology of transformation groups

Michael Brandenbursky, MichaÅ Marcinkowski

Let $M$ be an oriented smooth manifold, and $Homeo (M, I ¨ )$ the group of measure preserving homeomorphisms of $M$ , where $I ¨ $ is a finite measure induced by a volume f…
